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.
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!
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.
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.
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 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!
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.
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
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.
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
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 $$!!
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.
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
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
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.
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"
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.
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
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!
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.
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.
I got excited when the RX-8 was mentioned, nobody talks about them. hardly anyone near me has one, wish there was more for me to see to decide where my build should go with mine.
+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
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.
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
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.
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".
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.
all a natural asperation motor needs is a small air compressor very similar to a nos kit, injected right in front of the mass air flow. instant boost and the computer will adjust the fuel pressure. if done right, you will find about three psi during compression. depending on the engine, it amounts to about five horse and ten tourqes
You guys should put a cold air intake on a highly restricted, inexpensive and low performance but not utterly pathetic car and see if it makes a difference. Like a Toyota Matrix or something.
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...
Do a video on short ram intake vs stock airbox. I'd be interested to see what the difference is between the hot engine air and the cold outside air. I live in a place with lots of puddles so a CAI is dangerous for my car as it can suck up water if I hit one of those puddles. For this reason a SRI is my only option if I want to stay n/a. On that note, keep up the good work guys! Love the videos you produce.
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.
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.
+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...
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.
You guys should read the "David Vizard" books, you will learn a lot about flow, pressure and temperature effects, even though his old works are mostly orientated around naturally-aspirated.
I have been a fan of this show for a long time, and seeing how much M likes small cheap cars, how about modding an old Peugeot 106? They are cheap to modify and are such good starter cars for all young modders!
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.
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?

These make a bigger difference at higher altitude where the air is less dense. Getting colder denser air makes a bigger improvement then. At sea level, or low elevation, the air is already more dense so the results will most likely be less dramatic.
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.
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.
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.
It all depends on the car and the ECU. The ecu might know if there is denser cooler air but if the ecu can't advance ignition timing to make use of increased air you won't make any gains. There is no blanket rule for all cars, as with anything.
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.... .
+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.
You can't say its 2 or 3 stroke engine because there aren't any. Its an otto-cycle engine, that behaves similarly to a 2 stroke, as in on the opposite side of the Piston/Rotor another part of the otto-cycle is taking place.
What tuning fork most likely meant was it kind of works like a two stroke in terms of how the fuel, air and oil is mixed together in the combustion chamber to lubricate the apex seals. oh and the same 'thirstyness' as a two stroke lol
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.
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.
One thing not mentioned and quite difficult to prove - negative effect on the durability of the engine... If the aftermarket filter has larger pores, it will let more dust particles into the engine.. That's the only reason I don't put an aftermarket filter on my car, since there are a lot of gravel roads in Latvia :D
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)
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.
I designed a ram air/cold air intake system on my mustang and it dropped IAT's by a shit ton and kept them low even after long drives, way easier to tune when IAT's are consistent

That’s gold
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 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!
3 to 5 kilowatts = 4 to 6.7 horsepower.
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.
Those pushing electric cars want all us petro heads used to talking about power in terms of kilowatts. Subtle, but obvious.

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 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!
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.
I would say the resounding answer should be "it depends", a theme they glossed over last time around.
Last time I looked at a friend's RX8 it was a WANKEL ROTARY and NOT A 2 STROKE!!
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?
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.

Gee golly does he like the same show you like?
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...
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
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 $$!!
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.

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
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.
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
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.
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.
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.
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 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.
Drop in K&N Improved my hwy MPG by about 2 mpg on average.
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
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!
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.
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.

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.
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
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.
Please tell me where you see an "r" in Honda.
Toyoter Honder Mazder
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".
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!
all a natural asperation motor needs is a small air compressor very similar to a nos kit, injected right in front of the mass air flow. instant boost and the computer will adjust the fuel pressure. if done right, you will find about three psi during compression. depending on the engine, it amounts to about five horse and ten tourqes
You guys should put a cold air intake on a highly restricted, inexpensive and low performance but not utterly pathetic car and see if it makes a difference. Like a Toyota Matrix or something.
+DesolatorMagic I did it on my corolla, it feels like it has more power (or it could just be my in head) but I did see significant mileage increases
@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
moog, please take that horrible sticker off.
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
Do a video on short ram intake vs stock airbox. I'd be interested to see what the difference is between the hot engine air and the cold outside air. I live in a place with lots of puddles so a CAI is dangerous for my car as it can suck up water if I hit one of those puddles. For this reason a SRI is my only option if I want to stay n/a. On that note, keep up the good work guys! Love the videos you produce.
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.
CAI systems are noisy.....which can adversely affect your hearing over time....which causes you to SHOUT all the time.....
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.
who the hell cares about kilowatts just show hp
+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...
+derek salinas it converts to about 171 HP. So he lost around 6 HP with the factory intake.
+9600GTMAN According to your conversion, A Bugatti Veyron doesn't even have a kilowatt of power.
9600GTMAN 1,341HP is what you expressed. Which is equal to 999.983kW. This means I "math". Plus, you will never find a Bugatty anywhere.
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.
The factory intake _is_ "cold".
If your engine is well tuned, you will see no benefit.
wankels arent two stroke. just because you put the oil in the fuel like in two stroke doesnt make them two stroke.
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.
You guys should read the "David Vizard" books, you will learn a lot about flow, pressure and temperature effects, even though his old works are mostly orientated around naturally-aspirated.
I have been a fan of this show for a long time, and seeing how much M likes small cheap cars, how about modding an old Peugeot 106? They are cheap to modify and are such good starter cars for all young modders!
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.
you didn't use the fan on tested on dino
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?

***** Sure on a S2000, maybe about 10,000 RPM, what about the standard V8's which only go to 6,000 RPM ?

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.
These make a bigger difference at higher altitude where the air is less dense. Getting colder denser air makes a bigger improvement then. At sea level, or low elevation, the air is already more dense so the results will most likely be less dramatic.
Watching this video in 2020 loving the circa 2014 plaid shorts
big big big shame on the guy who said the rotary engine is a two stroke engine....
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
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
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.
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.
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
"hondar S2000"
Yeah uk people also do this, so annoying, same as 'I'm sat in a car' makes no freaking sense.
Cool Breaking Bad shirt
I just installed a short ram intake with thermo wrap on my TSX K24a2 and it sure sounds great when vtec kicks in!
It all depends on the car and the ECU. The ecu might know if there is denser cooler air but if the ecu can't advance ignition timing to make use of increased air you won't make any gains. There is no blanket rule for all cars, as with anything.
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 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.
Rx8 a 2 stroke? first i heard of that. of all things its a 3 stroke
there is no such thing as a 3stroke. there are 2 stroke or 4 stroke engines. did you maybe mean each rotor has 3 faces?
You can't say its 2 or 3 stroke engine because there aren't any. Its an otto-cycle engine, that behaves similarly to a 2 stroke, as in on the opposite side of the Piston/Rotor another part of the otto-cycle is taking place.
thisnamebegreat It may have similar but it has 4 cycles like a normal engine so its 4 stroke
SolarFilms ►TKV I have said this, otto-cycle has four cycles, the use of the term stroke on a rotary would be incorrect.
What tuning fork most likely meant was it kind of works like a two stroke in terms of how the fuel, air and oil is mixed together in the combustion chamber to lubricate the apex seals. oh and the same 'thirstyness' as a two stroke lol
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.
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.
"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.
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
Wankel rotary engine are not 2 strokes!
One thing not mentioned and quite difficult to prove - negative effect on the durability of the engine... If the aftermarket filter has larger pores, it will let more dust particles into the engine.. That's the only reason I don't put an aftermarket filter on my car, since there are a lot of gravel roads in Latvia :D
The ending that Moog slapped on this was awesome. I loved the peaceful trash talk!
aussies say tuned funny, chewned lmao
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”
Scotty Kilmer doesn't approve
steven christopher 😂
He only approves Toyota
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.
I designed a ram air/cold air intake system on my mustang and it dropped IAT's by a shit ton and kept them low even after long drives, way easier to tune when IAT's are consistent
Stopped the video at 2:40 ''the rx8 is a 2stroke'' really!!!? No it really isnt! It's a Wankel Rotory Engine ,which is completely different!
