Here I thought I would be posting original content on testing a CAI on an NA engine, only to wake up to this fantastic video. Well, two is better than none. Great watch - I found similar results on my Acura Integra (no vtec yo). There was an increase in power on the top end.

I don't know why but I get this passive aggressive vibe between your channel and MCM. Although they probably filmed this before you filmed your video they seem to piggyback off of your ideas and its kind of unsettling.
Biggest improvement is the NOISE!! Love that intake sound, its also much more dynamic than the exhaust sound, very quiet at low throttle and loud at high throttle!
On older cars it’s not just noise because the factory intake is garbage compared to the new intakes. I threw a cold air intake from a keep Cherokee onto a Buick rendezvous and it made the acceleration so much faster after I removed that small box filter. You won’t get supercharger numbers but on an 06 car I guarantee you’ll get at least 10 hp because your car couldn’t breathe.
Watts come from Joules, a universal measurement of energy. The only system thats stupid is the Horsepower measurement, based on a dude testing with fucking pony's. The only idiot here is you, sorry for the bad news.
Pro tip for all of you looking to get a cold air intake. Buy a cheap CAI kit on ebay, you can find them for about $50. Then, measure the filter that comes with it and buy a K&N or AEM replacement filter that is the same size. Replace the filter and you're good to go, and you just got a high quality CAI for around $100.
+Travis Pfeifer Doesn't PVC offgas some nasty things when it gets hot? I used ABS to avoid that, but not 100% sure if it's actually a material concern. Worth looking up, though, would hate to foul up your MAF sensor or something with nasty PVC fumes.
+MrJamesonStyles I'm not sure if that's something anyone has looked into. PVC fumes and MAF function...best guess is it's more dangerous for humans. K&N filters do have confirmed problems for MAFs however. Increased gunk on them and all of your intake. If this is not all cleaned up, regularly paper is better. Paper may still be better even if it's all cleaned up. MAFs for example already fail a lot on my car, the count may be 1 or 2 less without a lot of K&N filter time. 5th MAF in 140k miles. (Though 1 was just because new from the factory it was messing up fuel trims.)
+MrJamesonStyles Plus, PVC offgas is at temperatues that my intakes don't get to, even in the hottest of my summers, so a nonissue in most NA car unless you're 110 degress F plus...I haven't witnessed the data that hot.
+DE “AutoBravado” Nichols you must live where it's cold all the time then cause my Camaro in the summer will easily see 140 idling in the hot 100 degree summer heat.
firts thing boost the s2k and second ypou should consider coming to millwaukee wisconsin or west allis wisconsin to be specific we have a great car scene here that marty will hate cuz hondas everywhere
Mighty Car Mods Clearly the people on your forums are god damn idiots and have ZERO clue how a car engine works. It's essentially a giant air pump. The better you can get a larger and colder charge into the engine the bigger the bang you're going to get. Bigger bang means more power, taking out the very restrictive factory intake which is more designed around keeping noise low than making better power is good step in getting a little extra horsepower.
I did a K&N intake on my 05 S2K AP2 and i noticed the gains for sure. A noticeable amount of low end torque and for sure higher power in the high end of the rev range. Plus the sound is worth every penny! Great vid!
i would love to see you guys do a cold air vs stock air box on a late 90s early 2000s car like a mercury grand marquis. this stock box is just that. a box with a flat square filter. lets see what us regular folks will get from cold air.
I know this comment is over 2 years old but: The British and Australian use an intrusive R. Any word that ends in an A, they will put an R on the end, if the word coming next starts with a vowel. "Honda car".... is normal, but if the word following starts with a vowel: "Hondar is nice".
Factory systems are cold air intake systems(most). All the aftermarket ones do is eliminate the noise baffling and smooth the air inlet a bit. If the factory air box is not restricted, the throttle body, cylinder heads and cam profile are the only way to increase airflow. Short term fuel trim will correct changes almost immediately, so there is no “lean advantage.”
My buddy had a cold air intake on his rx-8 and it made more power BUT, he also had a piggyback ecu, modified exhaust and the car was professionally tuned. It sounded like a beast until he blew the engine.
How about Torque? Cold air intake kits, with LARGER area air filters, not TINY POD filters do make more power, torque and better fuel economy. It improves much greater with a free flowing EXHAUST system to allow intake and exhaust system to be matched with efficiency and flow. Your mythbusting busted nothing, you put an overly small POD filter which does breathe the same as stock since it is sized TOO SMALL.
+Budget Boosting Okay, that's a very good test. You've given me an idea for another video. I did one on the right temperature of an intake and how to manipulate that, that it's not always about being colder, you can get too cold for your build, I did, depending on weather.
+Budget Boosting Even removing the intake and running the throttle body naked wouldnt increase airflow. You could put a 6 inch intake pipe on a stock engine and it wouldnt make a lick of difference, if it did it would be a negative effect. The first few seconds of the video actually described pretty accurately why factory intake systems are very efficient and effective.
floridabrn If Im not mistaken, didnt that Honda have other modifications done to it? A modified engine can certainly take advantage of more air flow. So using a modified car to test the results doesnt really explain whats happening.....an aftermarket intake on a stock engine will actually be worse, as you MIGHT gain 1-2HP at the very top end, but you will most likely however have less torque at the low end which will result in poor fuel economy and those high flow air filters will most likely shorten the engines life as well. 1-2HP isnt even a noticeable amount of power, and chances are the Dynos that show even that kind of improvement could have had other variables that triggered that difference.....your car will vary HP output just from the slight difference in the quality of the gas.
3:48 would a stock ECU work the way that hes describing but be programmed to assume it is working within the capacity of the factory intake. eg- if a fault like a dirty intake occurs the ecu will accommodate by lowering the fuel, however it wont accommodate INCREASE in air flow higher than expected from a brand new factory intake out of (manufacturer's) fear of lean spikes? For example on my car (turbo charged) when i first installed a larger SRI, i took the car for a short drive to test prior to a reflash of the ecu. car was EXACTLY the same. I changed to the new appropriate ECU map suited to the new intake and suddenly the response of the car was massively changed and some noticable increase to torque. Feedback would be great. Thanks :)
+brad ley I don't think rich spikes are nearly as dangerous as lean spikes, so I don't think the manufacturers would be too worried about that. For the example in your car, it may be that the reflashed ECU needed the new intake, more than the new intake needed the ECU map, if that makes any sense. In other words, the stock intake might have provided more than enough air for the stock ECU, but not enough air to get the most out of the new map, especially if it turned up the turbo boost pressure.
Yeah, they made a video of it laughing about it, saying it's a guide on how to add more horsepower using decals on your bonnet. Since then it stayed there, 'cuz you know... Performance lol
I came here to check if I should replace the air intake in my RX-8, thought it might be the same for most of the cars. THANK god you were talking SPECIFICALLY about the rx-8, right at the beggining of the video! Great help! Love ya guys!
A new intake tube and high flow filter in stock air box on my Chevy pickup resulted in almost 18+ hp and lb. Across the power range. Only created 2-3 hp at peak. But across the spectrum I noticed performance gains that were worth the small investment
The S2000, like you said, has a very efficient induction system. On a real world environment in the US, by that I mean lots of expressways and interstate highways, you will see a small increase on an Accord or Camry or another family car With a K&N snorkel system. You probably won't see anything noticeable with just a K&N with the factory air box. As for a true performance car, don't expect anything as the factory induction systems are all optimized.
I've got an '03 Protege5, and it's pretty upgraded for a N/A car. When I put the intake on, it was mostly out of boredom, and while the bottom end and mid range power were exactly the same, I definitely noticed a slight difference in the top end power. On top of that, it saves room in the engine bay, and it sounds cool...because race car
Wind provides much cooler air than a dinky fan in a dyno room. Wind also creates resistance as well.... I would say... buy a CAI if you like the better sound, the fact the filter is reusable and also buy a decent one, not some piece of junk off ebay .
But the point remains that even in a windless shop, the saw a gain in power, on an actual road it could have the potential for more power. Either way a lot of cars, mostly low end fuel efficient cars will see a loss of power from an intake, that isn't factory, because it changes the airflow, while the factory airbox was specifically designed for that engine. On performance cars, you'll see gains. But on a regular old Toyota Corolla you're probably losses a little bit.
Sports car? Yes. High Performance? Mmm: I'm not gonna say it's a high performance car. An AMG GT? That's something I'd say _that's_ high performance...

You're unlikely to see performance gains with a cold air kit on something more mundane either. In fact, didn't they do a pod filter test on the Blue Turd? while that isn't a cold intake feed system with the bonnet up and the dyno fan running at full tilt it showed no increase in power, in fact the factory intake made the most 'power'.
If you're chasing tenths of seconds on a drag strip maybe, which would be stupid to be doing on a naturally aspirated 4 cylinder car with less than like 100 kw to begin with. But you're not going to feel a difference unless you're making like 50< kw (67 horsepower), which why would you even waste time doing pseudo-performance mods on that trash of a car to begin with? And there's not really that many things you can do to a slow N/A car to get enough to feel something without just turbocharging it. Still a great result from a numbers standpoint, but not enough to matter
+bailey allaby first of all ford can suck my shifter and play with the lug nuts and all you ricers need to "drift" off a bridge or just drive into a ford dealer/ junkyard and just leave it there to rust away
Wow, 177hp at the wheel, that's about as much as my 96 Grand Cherokee. Kinda sad on my Jeep's part considering it's a 5.2L V8. After I installed my Cherry Bomb Turbo muffler, I got 7hp and 7tq more, couldn't believe it. 184hp, 239tq from a motor twice the size in a 4x4 that weighs 4000lbs with an outdated 4 speed auto. Next mod's a name brand chip(not a cheap ebay one like on an older episode).
Anthony You don't think I realized a difference in weight when I mentioned the Jeep weighing 4000lbs? Also, it's "their" not "there". Not as bad as Paddy's comment.... Paddy, I know it's outdated, if you read what I posted, I flat out said it's outdated. At the same time, I don't see many DOHC engines in top fuel drag racing. 8000hp from supercharged HEMI based engines.
Not really surprising. I think I read somewhere that the S2000 engine at the time had the most kw per cc of displacement for a NA engine. The Cherokee V8 is probably a tad overbuilt with reliability and low end torque in mind.
But if you know anything about s2000s you know they don't make any power with basic bolt-ons because from the factory they are already at peak performance only way to make power is to go force induction
idk you might get a tad bit more power on an older none performance car. the s2000 is designed with performance in mind. so its air intake is already performance oriented. take something else like a popular early 2000s late 90s honda civic dx. which its airbox is not made with performance in mind and you might get more of a noticeable gain.
I was wondering the same thing; why they chose sports cars that are already developed for power. why not use say an economy car/ car with a mor restristive system. like yhe guy said RX8's lose power if you mess with the air intake system which I have heard before, does mean all cars lose power if you change the parts that where "finely tuned from the factory." what I am saying is that they could have used a RX8 for this test and said cold airs make you lose power, look at the dyno results... also what about a car with a larger intake manifold? do you use the stock air box? pod? cold air? ram? Im not refuting, just putting the idea out there.
On my Integra DC2 R I reduced lots of weight by using J's Racing Intake system. Checked on the dyno, similar results to your video! As for losing power down in the low range RPMS, I can justify it because I reduced tons of weight from the car and the car doesn't feel sluggish at all down low rpms. As for sound...that's totally up to the driver's preference. Love your videos guys! My DC2 is 998 KG and generating 252 HP NA B20VTEC.
It all comes down to each individual car. If I expected to see gains, it would be on the top end of a naturally aspirated engine, but even that's not always the case. My car is a great example. It's a moderately modified (extensive cylinder head work, amongst other things) NA engine, and I've gone through all sorts of intake configurations. Bizarrely, with the factory intake in place, I get severe detonation in the midband, and really, really shitty gas mileage at highways speeds. Cold air intake, no power down low, but lots of noise. Ended up doing some custom 2.75" piping from the factory airbox to the throttle body, then modified the factory airbox from a 2" inlet diameter to a 3" inlet diameter, maintaining the forward resonator box, and the thing runs smooth as silk from bottom to top, and factory quiet to boot. Dyno numbers went from ~145hp (108kw) to ~180hp (134kw), with fuel economy around 25mpg city/38mpg highway. On a car originally rated for 19/28. Airflow isn't just about volume, density and speed. Four cylinder engines in particular benefit from the laminar flow created by a properly-tuned resonance control system. The turbulence created by removing intake resonators can negatively impact the performance of the engine, and its ability to properly burn fuel. The change in sound that you hear when installing a cold air intake or an aftermarket cone filter goes both ways. If you can hear it, it's traveled to your ear from inside the combustion chamber. The "rougher" the sound, the more turbulence in the intake air stream. On a fuel-injected engine, turbulence has a severe negative impact on wet flow characteristics. Food for thought. :-)
I really wish they did it for different cars to show the variety. For example, on my car the airbox generates massive amounts of vacuum at above 4K. The maker did this on purpose because the engine is design for performance, but the car is designed to be economical, so they restricted the air intake to stop people reving it up so quickly for better economies. The maker actually sell an official replacement that they use on their rally cars, and it transforms the engine
I agree. some factory cars have terrible intakes. Like the Camaro SS, LS1 cars and trucks. my Colorado picked up 1.1mpg by deleting the OEM resonator box. intake is loud as shit now, but MPG is MPG.
There is a benefit to installing some types of air filters, however. Some, like K&N for example, are washable and reusable. This will allow one to wash and reuse it many times, sparing one from having to buy new filters. Saves $$!!
Too many people don't realize that with some cold air intakes, you add 10 feet of tubing to draw air from the fender. When you do this the added restriction defeats any gains you would get from the colder air. The best intakes use large short tubing to an airbox that is fed separately.
+derek salinas as this is an australian channel with mostly australians watching, we do. i hate when shit is in hp because i only know kw. dont be such a douchebag.
+Sam Price U know what ur right i apologize dont mean to sound ignorant towards your countries car culture as I have respected Australians love for cars since the early 80s when I first saw mad max i apologize for my earlier comment...
David Hill you're not looking at it right. your typical piston engine has each cylinder on a different stage at any given time. for instance on an inline 4 every 90 degrees of crank rotation a different cylinder is firing. all 4 cylinders will have fired in a single crank rotation. to compare the rotary you should think of the 2 rotor engine like a 6 "cylinder" as each rotor has 3 sides in a different stage like the piston engine. 1 side has compressed and fired while a second has powered and is exhausting, and the third is intaking a fresh charge. the firing order alternates between rotor 1 and 2 (like the firing order jumps banks on a v6 or v8) the ONLY similarities between the wankel and a 2 stroke are higher power vs displacement and the insane rpm redline. both are from less friction, fewer moving parts, and mass meaning less energy lost from combustion ( linear motion to rotating motion = lots of friction as do timing belts / chains, camshafts + pushrods or followers and valves of which the rotary has none) there's more to it, but that's the broad strokes.
David Burton David, good explanation; thank you. Wikipedia has a good demonstration video of the Wankel cycle running, as well as youtube. I rebuilt a rotary engine back in 1975 when nobody knew anything about them. Seeing how the rotor moves about in the rotor housing along with the ring gear, stationary gear and eccentric shaft; it twisted & nearly broke my brain.
Sorry to say guys after all the work you put in but you are the right people who install the weather station in the cellar. Well, what would you expect to improve if the car stalls in the dyno ? who is gonna blow air in the duct for an atmospheric engine ? St. Peter ? I would expect you to put car on the race track or motorway and run it high speed so air be naturally blown into as is moving through. Speechless
hey guys I totally agree with u on this, ive owned corvettes , mustangs, Hondas, and the cold air intake is all bullshit. I actually felt my cars got worse gas milage on all cars and noticed nothing for a power gain. im with you guys u this cols air intakes is all bullshit. my 2 cents...
WOW 5 KW, so basically you have to drive the car at over the REV range around 5,000 to 7,000 RPM to feel anything, for what a car that you cant legally drive over the speed limit anyway ?
no just drive in a lower gear if you want to feel the extra power. German automatics have a kick down button on the floor that will put the car in the lowest acceptable gear when you put it to the floor.
I think this comment goes to show you don't know anything about an S2000 yet you're here commenting about the car as if you own one. If this is an AP1 red line comes in at 9k RPM and an AP2 comes in at 8k RPM, V-tec on a stock S2000 doesn't even kick in until around 5800-6k RPM. So no you wouldn't be driving it over the "rev range" you would be driving the car like it was made to be driven at higher RPM where the car makes most of it's power. I don't even know how to address the last part of your comment elaborate what that is supposed to mean? I think every car is illegal to drive over the speed limit last time I checked?

Hello, I am from Argentina and I own a chevy Cruze 1.8 aspirate, which brings in the interior of its original air filter box, an aerodynamic entrance of plastic of the type Intake. This funnel-shaped rounded entrance is on the clean side of the filter. From the dirty side of the filter enters the air that comes from below the gurda mud, this air enters through a small conduit with curves and very intricate. The modification I made, was to cut the plastic box containing the air filter on the side facing the car, the cut was like a window across the width of the box, which is almost not noticeable . Through this window, air now enters from the engine compartment to the filter, this volume of air adds to that coming from below the car. Conclusion ... my chevy improved in low and high notably, revolves quickly, something that has always criticized this car, is more agile at the time of departure and gained in elasticity when en route. The improvement was very significant, it is another car and all with just make a hole in the bottom of the original filter case. My next step will be to buy a K & N flat filter, which I think, will allow to increase even more the air flow. Comment: At the moment of acceleration you hear the sound produced by the Intake Kit.
Really good watch, I always thought that CAI didn't make a difference for many of the reasons you mentioned, I guess for now on I will let someone have it when they tell me "oh i can feel the increase in power"
On most cars removing the resonator would make the airflow uneven thus causing a hiccup effect going into the intake manifold/throttle body. A cold air intake will add HP to any system in which the stock design is restrictive and when the stock application was not built with a performance oriented design. Let's use a 1989 isuzu pick up for example,An AEM Cold air intake will improve hp by atleast 3HP because the stock system is not so good in terms of getting a good flow of air to the engine. Now let's take a Mitsubishi Eclipse GTS with the Factory improved upon induction system,Which was designed and troubleshooted to the best of the engineers abilities too make more power of the base GT model,this application already has excellent flow therefore your likely to not achieve any gains at all by tampering with the stock design. So I assure you all,that this video can be misleading and that Cold air intakes do add substantial power gains,AS LONG AS THE CARS NATURAL DESIGN HAS WEAK AIRFLOW
What you say doesn't make sense. What is a hiccup effect? Resonators provide tuning to sound and a specific power range. Cold air intakes will always improve power. I don't mean those cone air filters that draw air from the radiator or the engine bay. I am specifically speaking of any intake that draws air outside of the engine bay (ambient air).
However there are also tuning effects with resonators and length of the intake on NA cars. Replacing the stock intake with a bolt on cold air can reduce power if the tuning is lost. For the most power, draw ambient air and turn the intake for the power band you want
What the hell is a hiccup effect? I'm not just asking because of the fact that I've removed the intake resonator on many cars of mine/my friends and had nothing happen other than the car sounding better, as well as removing clutter from under the bumper, but because I have NEVER heard that term used in an automotive sense.
It also depends on the pipes you use and how far away/ size of the air filter. If you had a tiny filter and a small intake and make both bigger while making the tubes hold colder air without heating up it causes your car to naturally let more air into the engine in result your mass air flow sensor with tell the ECU to put more gas into the engine. That’s when you do it correctly. Most people do not they just buy the kit online and install it thinking they’ll gain 10hp.
It's a complement mod, for something that needs more potential. Tuning Fork is awesome. The only other thing is that some of the manufactures who make nice systems spend as much time as the manufacturers to produce an effective product. Love the show, love what you guys do.
Thank! It's time to save up some money and buy myself one of those cold air intake! Thanks for the videos. You saved my money on buying one of those small supercharger that doesn't actually work, and you let me know the cold air intake actually works on a naturally aspired engine. It is a good investment. I am going to get one in a few months!
What the guy said about the learning the engine does is very true. The engine will recalculate how much air the engine is taking in. Putting a CAI on your car will only really help if you get a tune with it. Yes a few horsepower will be gained without a tune but the combo can get you much more.
So how did you 'bust the myth' here guys? That was a crap CAI and it still made money. A really well designed.. dual inlet from the front bumper from big trumpets fed into the stock box will easily double those figures, probably triple and give you a cool 15Kw at the wheels. More over that setup will make the car sooooooooooooo much more drivable, tractable and generally easier to drive providing more toque and less vulnerable to incorrect gear selection. It won't choke the car when you are in too lower a gear, probably improve fuel economy (never measured it)...well the list of reasons NOT to do it are too short.....and the list of reason to do it are to numerous.. however I stress, short run intakes removing the factory box are unlikely to make any real difference as you need the cold air from the front.... .
Well obviously he has had it for a while and overtime cars do lose BHP, especially if you dont service it or keep an eye on things such as oil or engine coolant.
I put the K&N short ram (they call it a CAI) on my Accord coupe 6/6. I like the sound, the throttle feels nice. K&N includes a dyno sheet claiming roughly 7HP/7lbFt. It was worth it to me.
Stock paper filters on intakes also trap more debris which will help you with the life of your engine. High-flow performance filters are not as effective in capturing micro-debris. That debris builds up and can be seen later in the throttle. It's like shaving off your nose hairs, they are there for a reason, not crucial but with merit nonetheless. I swap my paper filters with K&N filters when I know I will redline and enjoy a nice drive. If you do keep your cold-air intakes... make sure you upkeep regularly.
Tuning Fork said that the RX-8 is a 2-stroke engine... but since it's a rotary it doesn't really have "strokes" does it? it's a rotor spinning in a chamber, not a piston in a cylinder. so calling it a 2-stroke wouldn't be correct, would it? correct me if I'm wrong
Aaron TheStud no its not a 2 stroke, it works "similar" to a 2 stroke. having intake and exhaust ports instead of valves that open and close. and "similar" to a 2 stroke the oil is directly injected into the combustion chamber instead of the oil being added to the fuel like a 2 stroke. and yes an aftermarket intake will rob the rx8 rotary engine of horsepower
they are 4 stroke. 4 stroke mean it sucks fuel then compresses it then the bang the exhaust. 2 stroke suck fuel in the combustion chamber at the end of the power stroke and exhausts on compression stroke
Figured I'd comment since this will likely be the most popular video on the subject for awhile....So I feel that CAI/SRI intakes are valuable depending on a few other factors, for starters diameter of the piping....I have a 3.5 Intake which is an upgrade over the pvc 2.5 stock tubing. I definitely noticed a difference especially when moving from a oiled to a dry filter. Another benefit of the upgrade was how it opened up a hole area of my car hidden by the intake box and mounts. I had an issue where my cold pipe kept popping off and I would need to pull over and spend 10-15 minutes removing the airbox to get to it in my car. I would imagine this design would only increase in heatsoak and hope that by opening it up, the air that would go to the stock airbox is instead traveling across the top of my engine, hopefully pulling heat out. Driving a Turbo down South is no joke. Of course the biggest selling point is visceral and changing the sound of your car so you can hear spool and bov (if no maf sensor) is a good way to enjoy the car without driving recklessly.
So gained power, lost weight, better sounding, and a better looking engine bay? Doesn't sound like any "myths" got busted here, sounds like everyones CAI actually is a real upgrade. Now try this test with a modified N/A engine and see how much more gains you get from a simple cold air intake vs a factory box. Not to mention a lot of cars have a mass air flow sensor, upgrading that, and a bigger throttle body, along with a CAI, and you will definitely see gains.
The reason I slapped a cold air intake on my MK5 DSG GOLF is the 100% gain in smile factor with the gulping of air I get, seeing as I can't put a BOV on it lol
yes omg i was like dafuck he saying i mean i guess he didnt want to explain rotary engines but dude you could say (rx8s have special engines so they need very controlled airflow and so the way the air enters is critical)
I built a H6 intake for my outback and gained one second from the quarter mile. But the rules i believe you should follow are make sure its sealed (be legal) and make sure you install your filter in a place which wont see water. If the car has a oxygen sensor make sure its as far from the throttle body to prevent revision and get a better meter on the air flow ;) Great myth busting guys :)
+Rudpavv Rudpavv This. Been driving civics for 5 years, something like 100k miles combined, literally never had a problem that wasn't my fault. Check engine never blinked on once before my 8th gen got smacked by an F150.
The lesson is understand the concept of Cold air intakes (CAI) and not easily fall for the after market products calling itself CAI or removing an Oem that is already CAI.
One thing worth mentioning, there must be a factory restriction in order for the cold air intake to actually help. You'll find a proper intake set up on more modern cars than on the older ones, but people keep doing the same things that used to work in spite of the fact that engines are engineered better than they were back in the day.
the other thing to remember is that the cars they did are preformance oriented cars were bolt on's don't do that much. On a civic or other commuter cars the gains will be bigger because the factor intake was designed with less preformance in mind.
Gauby i have that same question. i wanna put a cold air intake on my Lexus IS300 and K&N seems to be the one that caught my eye, but i wondering why it cost more then the others.
interesting fact, on my 1990 dodge w150 with the throttle body injected 360 pre-magnum motor i did gain a very noticeable increase in fuel milage and far better water/air separation when splashing around off road by getting rid of the stock round air cleaner and replacing it with the intake system and box off of a 2000 dodge durango with the magnum v8. seem to be leaps and bounds better with more square inches of air filter which by simple logic should mean less restriction at the filter itself. now on another note i used black rtv silicone at all the areas where air could leak leading from the throttle body to the filter which im sure helps as well.

Love that intake sound, its also much more dynamic than the exhaust sound, very quiet at low throttle and loud at high throttle!
On older cars it’s not just noise because the factory intake is garbage compared to the new intakes. I threw a cold air intake from a keep Cherokee onto a Buick rendezvous and it made the acceleration so much faster after I removed that small box filter. You won’t get supercharger numbers but on an 06 car I guarantee you’ll get at least 10 hp because your car couldn’t breathe.

Pro tip for all of you looking to get a cold air intake. Buy a cheap CAI kit on ebay, you can find them for about $50. Then, measure the filter that comes with it and buy a K&N or AEM replacement filter that is the same size. Replace the filter and you're good to go, and you just got a high quality CAI for around $100.
Build your own. Way cheaper. I used 3" PVC. ;)
+Travis Pfeifer Doesn't PVC offgas some nasty things when it gets hot?
I used ABS to avoid that, but not 100% sure if it's actually a material concern. Worth looking up, though, would hate to foul up your MAF sensor or something with nasty PVC fumes.
+MrJamesonStyles I'm not sure if that's something anyone has looked into. PVC fumes and MAF function...best guess is it's more dangerous for humans. K&N filters do have confirmed problems for MAFs however. Increased gunk on them and all of your intake. If this is not all cleaned up, regularly paper is better.
Paper may still be better even if it's all cleaned up. MAFs for example already fail a lot on my car, the count may be 1 or 2 less without a lot of K&N filter time. 5th MAF in 140k miles. (Though 1 was just because new from the factory it was messing up fuel trims.)
+MrJamesonStyles Plus, PVC offgas is at temperatues that my intakes don't get to, even in the hottest of my summers, so a nonissue in most NA car unless you're 110 degress F plus...I haven't witnessed the data that hot.
+DE “AutoBravado” Nichols you must live where it's cold all the time then cause my Camaro in the summer will easily see 140 idling in the hot 100 degree summer heat.

You need an entire firewall for some cars, some cars you just need a steering column and the interior infront of the seats.
Mighty Car Mods Clearly the people on your forums are god damn idiots and have ZERO clue how a car engine works. It's essentially a giant air pump. The better you can get a larger and colder charge into the engine the bigger the bang you're going to get. Bigger bang means more power, taking out the very restrictive factory intake which is more designed around keeping noise low than making better power is good step in getting a little extra horsepower.
I do not have a cog next to my subscribed is this cause I'm on an I pad?

It would be nice to have a test on the gas mileage, since that's supposed to be half the benefit.
@Anonymous me
It really depends on the car. Some intakes are perfect the way they are, some can be improved.
I did a K&N intake on my 05 S2K AP2 and i noticed the gains for sure. A noticeable amount of low end torque and for sure higher power in the high end of the rev range. Plus the sound is worth every penny!
Great vid!
i would love to see you guys do a cold air vs stock air box on a late 90s early 2000s car like a mercury grand marquis. this stock box is just that. a box with a flat square filter. lets see what us regular folks will get from cold air.
Come on, all the way 2000-2010 plain civil cars with like 2.0 motors, it’s more GAIN from 5 kW vs the race cars like S2000…

Is the first letter of "Repair Bill" when you put a big ass turbo without changing connecting rods or pistons.
In British-derived accents, there is an intervocalic R. "Honda cars" is not modified, but "Honda apples" would be
Honda comes from Japan and the R is a ninja letter. It is there you just can not see it. But it can see you.
Hodar.
I know this comment is over 2 years old but: The British and Australian use an intrusive R. Any word that ends in an A, they will put an R on the end, if the word coming next starts with a vowel. "Honda car".... is normal, but if the word following starts with a vowel: "Hondar is nice".
Factory systems are cold air intake systems(most). All the aftermarket ones do is eliminate the noise baffling and smooth the air inlet a bit. If the factory air box is not restricted, the throttle body, cylinder heads and cam profile are the only way to increase airflow.
Short term fuel trim will correct changes almost immediately, so there is no “lean advantage.”
I would say the resounding answer should be "it depends", a theme they glossed over last time around.
My buddy had a cold air intake on his rx-8 and it made more power BUT, he also had a piggyback ecu, modified exhaust and the car was professionally tuned. It sounded like a beast until he blew the engine.

How about Torque? Cold air intake kits, with LARGER area air filters, not TINY POD filters do make more power, torque and better fuel economy. It improves much greater with a free flowing EXHAUST system to allow intake and exhaust system to be matched with efficiency and flow. Your mythbusting busted nothing, you put an overly small POD filter which does breathe the same as stock since it is sized TOO SMALL.
+Budget Boosting i had the same idea. with the k&n typhoon system, an input for the maf-sensor is included.
i can´t see it anywhere in this video?
+Budget Boosting Okay, that's a very good test. You've given me an idea for another video. I did one on the right temperature of an intake and how to manipulate that, that it's not always about being colder, you can get too cold for your build, I did, depending on weather.
+Budget Boosting Even removing the intake and running the throttle body naked wouldnt increase airflow. You could put a 6 inch intake pipe on a stock engine and it wouldnt make a lick of difference, if it did it would be a negative effect. The first few seconds of the video actually described pretty accurately why factory intake systems are very efficient and effective.
+Nick Palaroan sooooo, you're just gonna ignore the results?
floridabrn
If Im not mistaken, didnt that Honda have other modifications done to it? A modified engine can certainly take advantage of more air flow. So using a modified car to test the results doesnt really explain whats happening.....an aftermarket intake on a stock engine will actually be worse, as you MIGHT gain 1-2HP at the very top end, but you will most likely however have less torque at the low end which will result in poor fuel economy and those high flow air filters will most likely shorten the engines life as well. 1-2HP isnt even a noticeable amount of power, and chances are the Dynos that show even that kind of improvement could have had other variables that triggered that difference.....your car will vary HP output just from the slight difference in the quality of the gas.
Cold air intake METHBusted episode. Eh? Eh? Los Pollos Hermanos...and...meth...Breaking Bad..mythbusted... K

Hehe, It's funny because we all get it. If only Heisenberg were here to see it :(
That is the first thing I noticed!!
Ishieness Don't forget MAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAD
3:48 would a stock ECU work the way that hes describing but be programmed to assume it is working within the capacity of the factory intake. eg- if a fault like a dirty intake occurs the ecu will accommodate by lowering the fuel, however it wont accommodate INCREASE in air flow higher than expected from a brand new factory intake out of (manufacturer's) fear of lean spikes?
For example on my car (turbo charged) when i first installed a larger SRI, i took the car for a short drive to test prior to a reflash of the ecu. car was EXACTLY the same. I changed to the new appropriate ECU map suited to the new intake and suddenly the response of the car was massively changed and some noticable increase to torque.
Feedback would be great. Thanks :)
fear of rich spikes sorry
+brad ley I don't think rich spikes are nearly as dangerous as lean spikes, so I don't think the manufacturers would be too worried about that.
For the example in your car, it may be that the reflashed ECU needed the new intake, more than the new intake needed the ECU map, if that makes any sense. In other words, the stock intake might have provided more than enough air for the stock ECU, but not enough air to get the most out of the new map, especially if it turned up the turbo boost pressure.
That stripe looks so out of place,sorry,just my opinion.
my thoughts exactly!
Looks like shit. Dunno why its still on the car.
Yeah, they made a video of it laughing about it, saying it's a guide on how to add more horsepower using decals on your bonnet. Since then it stayed there, 'cuz you know... Performance lol
VeiRoN Stripes were originally used as sight lines for the driver.
but the 2-tone looks funky.
I came here to check if I should replace the air intake in my RX-8, thought it might be the same for most of the cars. THANK god you were talking SPECIFICALLY about the rx-8, right at the beggining of the video! Great help! Love ya guys!
A new intake tube and high flow filter in stock air box on my Chevy pickup resulted in almost 18+ hp and lb. Across the power range. Only created 2-3 hp at peak. But across the spectrum I noticed performance gains that were worth the small investment
Ive got a 68 C10 that i wanna put an air intake on, would it actually help it any?
Drop in K&N Improved my hwy MPG by about 2 mpg on average.
Congrats on 1,000,000 subscribers! Your videos are amazing :)
The S2000, like you said, has a very efficient induction system. On a real world environment in the US, by that I mean lots of expressways and interstate highways, you will see a small increase on an Accord or Camry or another family car With a K&N snorkel system. You probably won't see anything noticeable with just a K&N with the factory air box. As for a true performance car, don't expect anything as the factory induction systems are all optimized.
They just showed in the video that the S2000 stock system sucks...
You guys just totally saved me from buying my RX8 a cold air intake! This channel is the best thing on youtube. You guys rock.
I bet youre glad you saved those pennies for the engine rebuild
I've got an '03 Protege5, and it's pretty upgraded for a N/A car. When I put the intake on, it was mostly out of boredom, and while the bottom end and mid range power were exactly the same, I definitely noticed a slight difference in the top end power. On top of that, it saves room in the engine bay, and it sounds cool...because race car
Last time I looked at a friend's RX8 it was a WANKEL ROTARY and NOT A 2 STROKE!!
On a dyno is not the same as on the road unless your dyno is inside a wind tunnel that is linking windspeed to the dyno speed.
Wind provides much cooler air than a dinky fan in a dyno room. Wind also creates resistance as well.... I would say... buy a CAI if you like the better sound, the fact the filter is reusable and also buy a decent one, not some piece of junk off ebay .
Save your money on the cai, paint your calipers red and gain 5kw 👌🏻
dinky fan lol
But the point remains that even in a windless shop, the saw a gain in power, on an actual road it could have the potential for more power. Either way a lot of cars, mostly low end fuel efficient cars will see a loss of power from an intake, that isn't factory, because it changes the airflow, while the factory airbox was specifically designed for that engine. On performance cars, you'll see gains. But on a regular old Toyota Corolla you're probably losses a little bit.
Like 7HP, that's awesome. Great video. Scott is great.
About 6.5HP actually... not so bad at the dyno.
about 6.7 to be exact, round up to 7 isn't absurd.
Nice video guys, nice to see the someone doing real world tests with a Dyno not just babbling why something does or does not work.
Thanks for doing this test and confirming the manufactures claims with detailed testing!
Once again, they've chosen a high performance vehicle to test this, which is probably the least likely to see an increase in power from an intake mod.
Sports car? Yes. High Performance? Mmm: I'm not gonna say it's a high performance car. An AMG GT? That's something I'd say _that's_ high performance...
You're unlikely to see performance gains with a cold air kit on something more mundane either. In fact, didn't they do a pod filter test on the Blue Turd? while that isn't a cold intake feed system with the bonnet up and the dyno fan running at full tilt it showed no increase in power, in fact the factory intake made the most 'power'.
5kw gain on a NA 4 cylinder engine is a great result actually
If you're chasing tenths of seconds on a drag strip maybe, which would be stupid to be doing on a naturally aspirated 4 cylinder car with less than like 100 kw to begin with. But you're not going to feel a difference unless you're making like 50< kw (67 horsepower), which why would you even waste time doing pseudo-performance mods on that trash of a car to begin with?
And there's not really that many things you can do to a slow N/A car to get enough to feel something without just turbocharging it.
Still a great result from a numbers standpoint, but not enough to matter
not to mention it s four banger. strap one to a v8 and its much more noticable
every Honda needs a air intake to bring out the vtec noise
Every Honda needs to go in the trash.😂 #chevrolet

Wow, 177hp at the wheel, that's about as much as my 96 Grand Cherokee. Kinda sad on my Jeep's part considering it's a 5.2L V8. After I installed my Cherry Bomb Turbo muffler, I got 7hp and 7tq more, couldn't believe it. 184hp, 239tq from a motor twice the size in a 4x4 that weighs 4000lbs with an outdated 4 speed auto. Next mod's a name brand chip(not a cheap ebay one like on an older episode).
It ways about 1,000 lbs lighter ... Hate when people have to compare there v8s just stop
thats cuz you have an american piece of shit v8. old outdated shit. lol
Anthony Weighs, moron.
Anthony
You don't think I realized a difference in weight when I mentioned the Jeep weighing 4000lbs? Also, it's "their" not "there". Not as bad as Paddy's comment....
Paddy, I know it's outdated, if you read what I posted, I flat out said it's outdated. At the same time, I don't see many DOHC engines in top fuel drag racing. 8000hp from supercharged HEMI based engines.
Not really surprising. I think I read somewhere that the S2000 engine at the time had the most kw per cc of displacement for a NA engine. The Cherokee V8 is probably a tad overbuilt with reliability and low end torque in mind.
Watching this video in 2020 loving the circa 2014 plaid shorts
But if you know anything about s2000s you know they don't make any power with basic bolt-ons because from the factory they are already at peak performance only way to make power is to go force induction
idk you might get a tad bit more power on an older none performance car. the s2000 is designed with performance in mind. so its air intake is already performance oriented. take something else like a popular early 2000s late 90s honda civic dx. which its airbox is not made with performance in mind and you might get more of a noticeable gain.
I agree 👍
I was wondering the same thing; why they chose sports cars that are already developed for power. why not use say an economy car/ car with a mor restristive system. like yhe guy said RX8's lose power if you mess with the air intake system which I have heard before, does mean all cars lose power if you change the parts that where "finely tuned from the factory." what I am saying is that they could have used a RX8 for this test and said cold airs make you lose power, look at the dyno results... also what about a car with a larger intake manifold? do you use the stock air box? pod? cold air? ram? Im not refuting, just putting the idea out there.
"Los Pollos Hermanos" shirt!!!!!!!!!!!!! Moog you just got huge major cool points for being a Breaking Bad fan!!!! XD
anyone else notice??????
Glad to see that you guys got less biased and more scientific on your testing. Enjoy all y'all's content though!
On my Integra DC2 R I reduced lots of weight by using J's Racing Intake system. Checked on the dyno, similar results to your video! As for losing power down in the low range RPMS, I can justify it because I reduced tons of weight from the car and the car doesn't feel sluggish at all down low rpms. As for sound...that's totally up to the driver's preference. Love your videos guys! My DC2 is 998 KG and generating 252 HP NA B20VTEC.
wankels arent two stroke. just because you put the oil in the fuel like in two stroke doesnt make them two stroke.
It all comes down to each individual car. If I expected to see gains, it would be on the top end of a naturally aspirated engine, but even that's not always the case.
My car is a great example. It's a moderately modified (extensive cylinder head work, amongst other things) NA engine, and I've gone through all sorts of intake configurations. Bizarrely, with the factory intake in place, I get severe detonation in the midband, and really, really shitty gas mileage at highways speeds. Cold air intake, no power down low, but lots of noise. Ended up doing some custom 2.75" piping from the factory airbox to the throttle body, then modified the factory airbox from a 2" inlet diameter to a 3" inlet diameter, maintaining the forward resonator box, and the thing runs smooth as silk from bottom to top, and factory quiet to boot. Dyno numbers went from ~145hp (108kw) to ~180hp (134kw), with fuel economy around 25mpg city/38mpg highway. On a car originally rated for 19/28.
Airflow isn't just about volume, density and speed. Four cylinder engines in particular benefit from the laminar flow created by a properly-tuned resonance control system. The turbulence created by removing intake resonators can negatively impact the performance of the engine, and its ability to properly burn fuel. The change in sound that you hear when installing a cold air intake or an aftermarket cone filter goes both ways. If you can hear it, it's traveled to your ear from inside the combustion chamber. The "rougher" the sound, the more turbulence in the intake air stream. On a fuel-injected engine, turbulence has a severe negative impact on wet flow characteristics.
Food for thought. :-)
fantastic post!
I really wish they did it for different cars to show the variety. For example, on my car the airbox generates massive amounts of vacuum at above 4K. The maker did this on purpose because the engine is design for performance, but the car is designed to be economical, so they restricted the air intake to stop people reving it up so quickly for better economies. The maker actually sell an official replacement that they use on their rally cars, and it transforms the engine
What car was that testing done on rhkips?
I agree.
some factory cars have terrible intakes.
Like the Camaro SS, LS1 cars and trucks.
my Colorado picked up 1.1mpg by deleting the OEM resonator box.
intake is loud as shit now, but MPG is MPG.
Sanic That's a lot of money saved in the long run, good job!
would it make a difference if the car was moving? so the air would have more flow into the engine bay? I am sorry for my ignorance on this subject.
Yummysauce is god didn't hear anything like a fan and considering this that this car would be going almost full speed the air would be very very loud
There is a benefit to installing some types of air filters, however. Some, like K&N for example, are washable and reusable. This will allow one to wash and reuse it many times, sparing one from having to buy new filters. Saves $$!!
Too many people don't realize that with some cold air intakes, you add 10 feet of tubing to draw air from the fender. When you do this the added restriction defeats any gains you would get from the colder air. The best intakes use large short tubing to an airbox that is fed separately.

Wankel stroke engine = Intake, compression, power, exhaust. = 4 STROKE!
2 stokes mean a gas/oil mixuture. So Just Intake and exhaust strokes cuz they travel so fast
David Hill
Yes exactly david.
David Hill you're not looking at it right. your typical piston engine has each cylinder on a different stage at any given time. for instance on an inline 4 every 90 degrees of crank rotation a different cylinder is firing. all 4 cylinders will have fired in a single crank rotation. to compare the rotary you should think of the 2 rotor engine like a 6 "cylinder" as each rotor has 3 sides in a different stage like the piston engine. 1 side has compressed and fired while a second has powered and is exhausting, and the third is intaking a fresh charge. the firing order alternates between rotor 1 and 2 (like the firing order jumps banks on a v6 or v8) the ONLY similarities between the wankel and a 2 stroke are higher power vs displacement and the insane rpm redline. both are from less friction, fewer moving parts, and mass meaning less energy lost from combustion ( linear motion to rotating motion = lots of friction as do timing belts / chains, camshafts + pushrods or followers and valves of which the rotary has none) there's more to it, but that's the broad strokes.
David Burton
David, good explanation; thank you.
Wikipedia has a good demonstration video of the Wankel cycle running, as well as youtube.
I rebuilt a rotary engine back in 1975 when nobody knew anything about them.
Seeing how the rotor moves about in the rotor housing along with the ring gear, stationary gear and eccentric shaft; it twisted & nearly broke my brain.
Dr.Anderson you're welcome. Happy to help.

Sorry to say guys after all the work you put in but you are the right people who install the weather station in the cellar. Well, what would you expect to improve if the car stalls in the dyno ? who is gonna blow air in the duct for an atmospheric engine ? St. Peter ?

hey guys I totally agree with u on this, ive owned corvettes , mustangs, Hondas, and the cold air intake is all bullshit. I actually felt my cars got worse gas milage on all cars and noticed nothing for a power gain. im with you guys u this cols air intakes is all bullshit. my 2 cents...
They look nice though. Really sucks that it does no good
WOW 5 KW, so basically you have to drive the car at over the REV range around 5,000 to 7,000 RPM to feel anything, for what a car that you cant legally drive over the speed limit anyway ?
no just drive in a lower gear if you want to feel the extra power. German automatics have a kick down button on the floor that will put the car in the lowest acceptable gear when you put it to the floor.
I think this comment goes to show you don't know anything about an S2000 yet you're here commenting about the car as if you own one. If this is an AP1 red line comes in at 9k RPM and an AP2 comes in at 8k RPM, V-tec on a stock S2000 doesn't even kick in until around 5800-6k RPM. So no you wouldn't be driving it over the "rev range" you would be driving the car like it was made to be driven at higher RPM where the car makes most of it's power.
I don't even know how to address the last part of your comment elaborate what that is supposed to mean? I think every car is illegal to drive over the speed limit last time I checked?

You win my brain hurts trying to reason with you. I am sure someone else has more patience and will chime in to help you.
Hello, I am from Argentina and I own a chevy Cruze 1.8 aspirate, which brings in the interior of its original air filter box, an aerodynamic entrance of plastic of the type Intake. This funnel-shaped rounded entrance is on the clean side of the filter. From the dirty side of the filter enters the air that comes from below the gurda mud, this air enters through a small conduit with curves and very intricate. The modification I made, was to cut the plastic box containing the air filter on the side facing the car, the cut was like a window across the width of the box, which is almost not noticeable . Through this window, air now enters from the engine compartment to the filter, this volume of air adds to that coming from below the car. Conclusion ... my chevy improved in low and high notably, revolves quickly, something that has always criticized this car, is more agile at the time of departure and gained in elasticity when en route. The improvement was very significant, it is another car and all with just make a hole in the bottom of the original filter case. My next step will be to buy a K & N flat filter, which I think, will allow to increase even more the air flow. Comment: At the moment of acceleration you hear the sound produced by the Intake Kit.
Really good watch, I always thought that CAI didn't make a difference for many of the reasons you mentioned, I guess for now on I will let someone have it when they tell me "oh i can feel the increase in power"
keep the stock airbox and plumbing but remove the resonator. i bet the number goes back to what the cold air was making
Why?
On most cars removing the resonator would make the airflow uneven thus causing a hiccup effect going into the intake manifold/throttle body.
A cold air intake will add HP to any system in which the stock design is restrictive and when the stock application was not built with a performance oriented design.
Let's use a 1989 isuzu pick up for example,An AEM Cold air intake will improve hp by atleast 3HP because the stock system is not so good in terms of getting a good flow of air to the engine.
Now let's take a Mitsubishi Eclipse GTS with the Factory improved upon induction system,Which was designed and troubleshooted to the best of the engineers abilities too make more power of the base GT model,this application already has excellent flow therefore your likely to not achieve any gains at all by tampering with the stock design.
So I assure you all,that this video can be misleading and that Cold air intakes do add substantial power gains,AS LONG AS THE CARS NATURAL DESIGN HAS WEAK AIRFLOW
What you say doesn't make sense. What is a hiccup effect? Resonators provide tuning to sound and a specific power range.
Cold air intakes will always improve power. I don't mean those cone air filters that draw air from the radiator or the engine bay. I am specifically speaking of any intake that draws air outside of the engine bay (ambient air).
However there are also tuning effects with resonators and length of the intake on NA cars. Replacing the stock intake with a bolt on cold air can reduce power if the tuning is lost.
For the most power, draw ambient air and turn the intake for the power band you want
What the hell is a hiccup effect?
I'm not just asking because of the fact that I've removed the intake resonator on many cars of mine/my friends and had nothing happen other than the car sounding better, as well as removing clutter from under the bumper, but because I have NEVER heard that term used in an automotive sense.
Damn, I caught the video early, too bad I don't have anything witty to say
you didn't use the fan on tested on dino
It also depends on the pipes you use and how far away/ size of the air filter. If you had a tiny filter and a small intake and make both bigger while making the tubes hold colder air without heating up it causes your car to naturally let more air into the engine in result your mass air flow sensor with tell the ECU to put more gas into the engine. That’s when you do it correctly. Most people do not they just buy the kit online and install it thinking they’ll gain 10hp.
It's a complement mod, for something that needs more potential. Tuning Fork is awesome. The only other thing is that some of the manufactures who make nice systems spend as much time as the manufacturers to produce an effective product. Love the show, love what you guys do.
I want to make my 2002 cavalier as fast as possible. Where should i start?
sell it.
TheLongboardLife LOL 😂
Take it to get recycled and with the money you get for the metal or whatever "old gm" made it out of buy an s2000 ;)
Drop it from a great height...? lol
Pushing it off a cliff
CAI systems are noisy.....which can adversely affect your hearing over time....which causes you to SHOUT all the time.....
@mightycarmods do a frozen air intake by wrapping the intake with a c02 charged copper coil and insulating the whole thing
Yes, I've been wanting to see this done
Thank! It's time to save up some money and buy myself one of those cold air intake! Thanks for the videos. You saved my money on buying one of those small supercharger that doesn't actually work, and you let me know the cold air intake actually works on a naturally aspired engine. It is a good investment. I am going to get one in a few months!
What the guy said about the learning the engine does is very true. The engine will recalculate how much air the engine is taking in. Putting a CAI on your car will only really help if you get a tune with it. Yes a few horsepower will be gained without a tune but the combo can get you much more.
moog, please take that horrible sticker off.
So how did you 'bust the myth' here guys?
That was a crap CAI and it still made money. A really well designed.. dual inlet from the front bumper from big trumpets fed into the stock box will easily double those figures, probably triple and give you a cool 15Kw at the wheels.
More over that setup will make the car sooooooooooooo much more drivable, tractable and generally easier to drive providing more toque and less vulnerable to incorrect gear selection.
It won't choke the car when you are in too lower a gear, probably improve fuel economy (never measured it)...well the list of reasons NOT to do it are too short.....and the list of reason to do it are to numerous..
however I stress, short run intakes removing the factory box are unlikely to make any real difference as you need the cold air from the front.... .
I guarantee you that nobody has read your comment :)
SlazerFis I read it. :)
Kryxel Then you're a nobody :)
+SlazerFis I read it too ;]
how can a 240 hp S2K make around 180hp ?
Well obviously he has had it for a while and overtime cars do lose BHP, especially if you dont service it or keep an eye on things such as oil or engine coolant.
ok it make sense now
180hp at the wheels, 240 at the fly
Time is a bitch :P
Thats 180 at the wheels I believe
I put the K&N short ram (they call it a CAI) on my Accord coupe 6/6. I like the sound, the throttle feels nice. K&N includes a dyno sheet claiming roughly 7HP/7lbFt. It was worth it to me.
Stock paper filters on intakes also trap more debris which will help you with the life of your engine. High-flow performance filters are not as effective in capturing micro-debris. That debris builds up and can be seen later in the throttle. It's like shaving off your nose hairs, they are there for a reason, not crucial but with merit nonetheless. I swap my paper filters with K&N filters when I know I will redline and enjoy a nice drive. If you do keep your cold-air intakes... make sure you upkeep regularly.
I once put a sticker on my honda, it added +5HP.
Is that all?.... you can get way more with good quality ones, especially if red in color.
The factory intake _is_ "cold".
If your engine is well tuned, you will see no benefit.
Tuning Fork said that the RX-8 is a 2-stroke engine... but since it's a rotary it doesn't really have "strokes" does it? it's a rotor spinning in a chamber, not a piston in a cylinder. so calling it a 2-stroke wouldn't be correct, would it? correct me if I'm wrong
Aaron TheStud no its not a 2 stroke, it works "similar" to a 2 stroke. having intake and exhaust ports instead of valves that open and close. and "similar" to a 2 stroke the oil is directly injected into the combustion chamber instead of the oil being added to the fuel like a 2 stroke. and yes an aftermarket intake will rob the rx8 rotary engine of horsepower
they are 4 stroke. 4 stroke mean it sucks fuel then compresses it then the bang the exhaust. 2 stroke suck fuel in the combustion chamber at the end of the power stroke and exhausts on compression stroke
Lets start from the beginning. Wankel doesn't "stroke" it rotates. Plus all the cycles happen simultaneously. Joe has a valid point.
Figured I'd comment since this will likely be the most popular video on the subject for awhile....So I feel that CAI/SRI intakes are valuable depending on a few other factors, for starters diameter of the piping....I have a 3.5 Intake which is an upgrade over the pvc 2.5 stock tubing. I definitely noticed a difference especially when moving from a oiled to a dry filter. Another benefit of the upgrade was how it opened up a hole area of my car hidden by the intake box and mounts. I had an issue where my cold pipe kept popping off and I would need to pull over and spend 10-15 minutes removing the airbox to get to it in my car. I would imagine this design would only increase in heatsoak and hope that by opening it up, the air that would go to the stock airbox is instead traveling across the top of my engine, hopefully pulling heat out. Driving a Turbo down South is no joke. Of course the biggest selling point is visceral and changing the sound of your car so you can hear spool and bov (if no maf sensor) is a good way to enjoy the car without driving recklessly.
So gained power, lost weight, better sounding, and a better looking engine bay? Doesn't sound like any "myths" got busted here, sounds like everyones CAI actually is a real upgrade.
Now try this test with a modified N/A engine and see how much more gains you get from a simple cold air intake vs a factory box.
Not to mention a lot of cars have a mass air flow sensor, upgrading that, and a bigger throttle body, along with a CAI, and you will definitely see gains.
The reason I slapped a cold air intake on my MK5 DSG GOLF is the 100% gain in smile factor with the gulping of air I get, seeing as I can't put a BOV on it lol
2:45 The RX8 Is two stroke??? O_o
yes omg i was like dafuck he saying i mean i guess he didnt want to explain rotary engines but dude you could say (rx8s have special engines so they need very controlled airflow and so the way the air enters is critical)
I guess technically... but it’s a stretch to call a rotary “2 stroke”
big big big shame on the guy who said the rotary engine is a two stroke engine....
Beautiful car ugly stripe.
Not your car
I built a H6 intake for my outback and gained one second from the quarter mile. But the rules i believe you should follow are make sure its sealed (be legal) and make sure you install your filter in a place which wont see water. If the car has a oxygen sensor make sure its as far from the throttle body to prevent revision and get a better meter on the air flow ;)
Great myth busting guys :)
You remember how you built the intake?
these guys deserve me punching the subscribe button in the face!!!!!
good videos...
did he really just say "Hi Power naturally aspirated engine"? never knew 177 horses were high power...
For a 4cyl 2 litre it is
+Cam Brown true that
chevyLsx my truck stock is about 300hp.
kw and hp are different. i own an s2k and a 5th gen ss. s2k is 240hp factory. ss is 426hp. the s2k is a more fun car tondrive hands down
No he meant to say he was high and the rest he tongue twisting making up words
How can you hate an S2000?
The one thing I don't like is the electronic mph on the gauge.
cradlerofdeath That's just minor.
Not to me i work a nightshift thats flooded with cops at nighttime when i go home.
hating on hondas is just a meme
+Rudpavv Rudpavv This. Been driving civics for 5 years, something like 100k miles combined, literally never had a problem that wasn't my fault. Check engine never blinked on once before my 8th gen got smacked by an F150.
Cool Breaking Bad shirt
The lesson is understand the concept of Cold air intakes (CAI) and not easily fall for the after market products calling itself CAI or removing an Oem that is already CAI.
Thanks for doing this guys, 3 years later lol
"since it's such a high powered car" Dyno shows 177 horse power at it's peak 😂😂
Power to weight
Punisher Hemi and it’s whp vs at the crank, just because a hellcat makes 710 ho at the crank doesn’t mean it’ll make it at the wheels.
Wankel rotary engine are not 2 strokes!
So how much is 5 kilowatts? Around 8 horsepower?
Not enough to feel, but enough to shave a few milliseconds off a quarter mile.
+Richard Jordan 6.7 HP
+Richard Jordan In 'Murica, we use HP as the standard...not kW....rwar!
+Richard Jordan goto google and type "5 kw to hp"
One thing worth mentioning, there must be a factory restriction in order for the cold air intake to actually help.
You'll find a proper intake set up on more modern cars than on the older ones, but people keep doing the same things that used to work in spite of the fact that engines are engineered better than they were back in the day.
the other thing to remember is that the cars they did are preformance oriented cars were bolt on's don't do that much. On a civic or other commuter cars the gains will be bigger because the factor intake was designed with less preformance in mind.
"hondar S2000"
Yeah uk people also do this, so annoying, same as 'I'm sat in a car' makes no freaking sense.
Planning on hooking one of these up on my G35? Is K&N worth the price? It seems to be $100+ more than any other brand.
Gauby i have that same question. i wanna put a cold air intake on my Lexus IS300 and K&N seems to be the one that caught my eye, but i wondering why it cost more then the others.
+Mario G Marketing.
+MrJamesonStyles And quality.
put it in hp nobody who watches uses kw
kupah horsepower
Moog you have one of the best shirts ever, LOS POLLOS HERMANOS!!!
interesting fact, on my 1990 dodge w150 with the throttle body injected 360 pre-magnum motor i did gain a very noticeable increase in fuel milage and far better water/air separation when splashing around off road by getting rid of the stock round air cleaner and replacing it with the intake system and box off of a 2000 dodge durango with the magnum v8. seem to be leaps and bounds better with more square inches of air filter which by simple logic should mean less restriction at the filter itself. now on another note i used black rtv silicone at all the areas where air could leak leading from the throttle body to the filter which im sure helps as well.
