Test: Does A Cold Air Intake Improve Performance?

- Well'p there was only one way to get to the bottom of this soooo... we got two of the exact same cars, hired some professional racecar drivers, and had them find out who is faster.
Pretty funny to see the results although it's about what I expected. Even if a cold air intake gave +10HP it really wouldn't be noticeable on a high horsepower car like this since that's such a small difference in terms of big power numbers.
Cold Air Intakes WILL NOT make your car faster. Case closed.

who the hell does a demo race at night? Can't even see what's going on
bellevernon15012 lol exactly
its called mexico racing league dummy illegal races
i can see very clearly maybe you need glasses or turn up the brightness
bellevernon15012 😹🤣😂😭
Exactly..lol
Not "cold air" that's a short ram with a heat shield. Cold air would be piped further away from engine. - Just sayin..
The Stock Box actually is a CAI, since it gets air from outside of the engine bay.
I always believe most car stock intake is CIA as they are all positioned to get air from outside of the car and with rubber or plastic pipes it will not hit up, the best thing is to change performance filter to reduce air restrictions
@@esoghumedominic13 , That is true. However, the best thing to do is to use the stock location and route, but upgrade to a smoother and even larger, unrestricted inlet/intake system.
Most stock boxes are cold air but the filter and tube are usually restrictive I myself have a 2013 RT 5.7, took the cold air off my truck for s&g and it gave my car an increase in power so much so that I had wheel hop. I also have an an exhaust system so that's probably why I saw better gains.
@@big_red_606 Wheel hop from 3-5 HP gain (if that)?
small world i go to that same track
From Starlight To Sunrise me too!!
Same here 👍
Eeeeee😂😂
"trained professionals on a closed course"
*drives on a normal road*
Neelo Tv I thought the same thing. Lol
Maybe they closed the street
Hell I'm a professional race car driver too than. Tomorrow I'm quitting my job and and going pro racecar lmao 🤣😆😂
Dumbest video I ever watched
obviously stated for legal reasons. No shit they are on a public road
dodge uses map tuning for their cars stock so without a retune for the new intake, you effectively gain 0hp
*Filmed in Mexico... great test man totally even
Still waiting on that +40whp dyno video ;)
Well I'll be dammed. I kind of agree with one of the first comments though.
"From reading various threads on this topic (no tune CAI's), after a number of drive cycles, the factory ECU will start to adjust for the CAI and the car will make the same or less power than when stock.
As the car detects knock, it will start to pull timing down to the low octane tables and eventually, I think you'll see that horsepower gain disappear."
So perhaps wait a bit before you do a dyno pull and see if the ECU corrects for different airflow. Either way that's pretty cool! Looking forward to your test!
***** I'll shit my pants if I see anything more than 20hp lol
lol I'd do the same
Hey
seems like any mod with out a tune is useless IMHO
i agree
Really depends, but yes, I agree as well. A tune is at least needed to achieve all the benefits.
I see this comment all the time. How would the tune let the intake make more power? The tune will add power in and of itself, more timing, different fueling, etc. A tune can correct for improper fueling, but this mod doesn't affect that, especially on a speed density car that runs in closed loop, where it can adjust on the fly for the fraction of a percent difference in fueling that there may be...
a tune makes a car run better intake or not so you'll see a gain from a tune no matter what unless of course its a crap tune
If the intake by itself offers 0hp, and a tune offers 20hp, then both will net you 20hp
Intake = 0 HP
Tune = 20 HP
+
--------------------------
Intake and Tune = 20 hp
The tune offers gains in and of itself, by increasing timing, or changing commanded fueling etc. The tune does not let the motor take advantage of the intake, all it does is correct fueling on a MAF based car when the MAF housing diameter on new intake is larger than stock. This is not a case of this, as this is a speed density based car. Even in the case of a MAF based car accounting for the intake in the tune just adjusts the airflow model to keep the car safe.
I love when people tell me how much faster their car is with just a CAI haha
I wasn't surprised either. What you have is a SHORT RAM not a CAI. A CAI will be routed down your wheel well. This video is invalid.
TONY LARIOS That's exactly what I said! He doesn't even have a CAI... what an idiot
TONY LARIOS I have noticed the words "cold air intake" gets thrown around loosely without those knowing about it. And there are videos out there explaining differences between short ram air intake and cold air intake. Message to the dude shooting the video; definitely short ram intake. Take yourself to Engineering Explains for further information.
Except most people call what he has a CAI... including the manufactures... and all cars come stock with a CAI
Man Riley u make the best videos. Every video you make helps man..keep up the good work!!!
datboibg21 have you been drinking that was terrible
That's not a cold air intake that's just a short ram with a heat shield. So many people think that these are CAI but they are NOT!
I would assume with a good tune and that intake it would make a difference.
Thanks for a take on cold-air intakes that is completely MISSING on the internet! Looking back at 6 years now, which cold-air intake would you recommend for a 2022 Charger GT (v6) at this point? Thanks again for sharing!
Just a thought with my car (evo x) an intake mounted in the engine bay is considered a short ram intake. A cold air intake puts the filter out of the engine bay usually in the fender well wonder if it would make a difference being mounted in the fender well (colder air)
This is not CAI vs Stock. This is SRI vs stock. Correct me if I'm wrong but I'm pretty sure short rams are better for low end power because of the hot air it is getting from the engine verses a true cold air intake is better for high end power. Therefore short ram will give you the same as stock but will increase torque slightly and increase mpg slightly as well. Cold air intakes will increase hp and torque by roughly 5-8? By the way for you people wondering about cold air intakes, colder air means denser air. Denser air means more power. But you have to remember to tune your ecu properly to except that denser air and distribute the air and fuel ratio correctly or else your just making the current air cooler and the same fuel is being added so nothing drastic will improve. Only slight improvements.
I love your scat man, The purple is so dope!! Nice vid!
Also the purple one has a front strut brace, and it is not mentioned that it has a lowering kit so i assume it does not but the blue one does. You must factor in weight and even the tire weight, rim weight, how much fuel you were carrying in both.
Indeed. A lowered car is a slicker car through the air. Never mind the variances in HP from car to car. This test only works if 2 unmolested cars equal out on the dyno and then swap in the CAI.
it all depends on the car type, and the kind of cold air intake. Some cars benefit from it while others dont. And by the way that intake was a short ram type not a real cold air intake that goes into the fender well so youre still pulling hot air....
Great Video ! Love you're car man please upload more videos of you're exhaust and Top speed keep up the good work !
is there an air intake that directs air to the cold air intake ? like scoop leading somewhere to the front of the car to grab the air in direct it in or just sitting there and natural air making it way there is all there is ?
cool video bro! 2 questions though,so do you have a mid muffler delete with or without resonators? and did it affect performance in any way? loss of torque etc....
RichardTheGreat I did a mid muffler delete and resonator delete the resonator delete made me lose a ton of power I put the resonators back on kept the mids off car ran great resonator delete made me lose alot of back pressure 😤
There is a possibility that certain engine layouts/sizes would have increased performance gains over stock, compared to other layouts and engine sizes. A large engine like the 5.7l hemi may not gain much from a CAI bolt on. But smaller engines from 1.8l to 3.6l seem to show a bit more punch somewhere in the powerband.
tbh, the minor difference a CAI might make would be countered by the reduced rolling mass of the smaller tires on the other car, so that might explain why they were basically identical in performance.
Nope.. the explanation is that these intakes are a scam and do nothing on modern engines. The companies that make them flat out lie.
+L A CMPNY not sure where you get your information but you couldn't be more wrong. These after market intakes do not provide more air flow that stock. They simply don't. Where are you getting your information from?
Besides, the stock intake is capable of providing more air than this engine could ever consume. Who told you it couldn't? Why do you think there is a restriction here? (Btw and some point in moving up in power, the first restriction in airflow will be the heads)
But again.. I really want to know where you've received your information? You sound like a KN commercial student lol.
+L A CMPNY you can only tune in about 20 more hp on this particular engine You will get that 20 hp by allowing more fuel and air into the engine. The filter has nothing to do with it. Stock filter, aftermarket filter, hell take the filter right out and it's not going to change anything. You will have the same amount of air being vacuumed into the cylinder either way. You don't seem to understand that the stock filter has more the capacity to supply more air than the engine will ever need.
+L A CMPNY wow.. Lol. Uhmmm.. Ok. I'll leave you with your own thoughts then.
If want to talk, please let me know how many cfm of air this engine uses to make 485 hp? Then tell me how much air the stock filter is capable of flowing? How many cfm's of air is required to make another 100hp? Another 200hp. You don't seem to understand that the stock filter has way more capacity than what the cylinders could ever draw in! You simply don't understand any of it because you don't have the numbers. Anyway.. can't teach someone who isn't willing to learn. I'm done.
+Sp 485 Air intakes make sense when you have an engine (like upgraded) that needs more air to produce the maximum power...
A friend of mine bought a Lexus LC 500 and we wanted to install a cold air intake system but the naturally aspirated v8 it has is already fitted with dual air intakes stock. So theoretically speaking, if you where to replace the stock filters with twin cold air intakes would that double the hp given from just one intake ? Or would it be the same as having one cold air intake?
I always find that my cold air intake performs better in the winter months when the air is cooler . you should do this test video again this winter coming up . to see the results
I notice every time I install a cold air intake in my car it always ruin my engine in the long run
It's all dependent on the car . Some it's just worth staying stock
Yeah I think I'll stick with my K&N drop in filter/ stock air box setup. Thanks for the comparison information buddy.
NANDO R/T yes! K&N drop in. Not to mention the open filter kills torque down low. So it was even at highway speed, but intake hurts low end. I wish it didn’t as I love how they look.
you do not have a cold air intake, u have a short ram air intake, idk why ppl can't tell the difference between the two
I think a lot depends on the engine. The big V-8’s already have enough torque and HP so an intake doesn’t make much difference. However when I installed a K & N Typhoon intake on my 2014 V-6 300C, I noticed a big difference in throttle response , passing power, and it knocked 3 tenths off my 0-60 time. The sound is also great and my car performs like it never did with the stock system. BTW, this improvement came without any exhaust or other mods, just the intake, so if you have a V-6 Mopar, try an intake, I think you’ll like the results!
Riley,
I just put a K&N cold air intake on my 2019 scat pack and noticed that the throttle response is better and the car is more throaty but my exhaust crackles and pops are gone especially when I rev the car at idle. Is this normal?
Thanks
So did it make your car faster
It’s a short ram intake not a cold air intake. The reason it’s dead even in that race is because you’re taking in hot air but at a higher rate. If you had a true cold air intake (air being taken from OUTSIDE the engine bay where HOT air is) you’d be making slightly more pretty ponies because the less restrictive air tube and high flow air filter WITH colder (more dense) air.
This and a short ram air intake like the one you have generally is only faster in low rpm ranges. Hence, why you kind of pulled slightly at the beginning of the race and then you evened out
Does a CAI upgrade need an ECU tune/upgrade? I have a 1998 Toyota Corolla GLi BTW. 4A-FE stock.
Thanks for the compliment on my precision driving skills.
I’ve seen a lot of dyno tests that showed cold air intake bringing power up quite a bit
Man......thanks a lot,your video has been very helpful to me......i used to wear a cold air intake on my Hyundai tiburon,the sound was great but i don't think the performance had changed,so i put back its genuine air filter....it has taken back it's lost torque.....it lost the sound but who cares about the sound??watching your video and having purchased a couple of cold air intakes i trully believe that i wasted my money just to get sound and not horse power as i believed i would......thanks again bro!!!!
What is a safe mileage to get the mid muffler delete?
hi i changed my original flat paper filter for a K&N drop in flat filter and i noticed the throttle response was much better and felt like a slight faster increase in acceleration.. im thinking now since im i will b adding software of removeing the original air filter box and going for a cold air intake.. do u think the K&Ncone filter will make a different compared to the flat K&N air filter in my stock air box?
chucked my mopar airbox for the oem with a dryflow filter. car actually feels smoother in town. less heat soak with oem box maybe? either way i got rid of it. my daily mpg hasnt changed either. just lost some noise...
really? at pitch dark night? unproven! only way you can prove this is on a dyno.!!
ANDY SEWELL wea
But i would have to say that even dyno tests are lab situations only!! Not real world based where wind mph, terrain, etc affect performance. Dynos are at one setting, opened hood (which lol you dont drive with your hood opened i suppose) and strapped on a wheel. So, even dynos can give u peak levels but not actual real moment situation results.
The air is not “colder” in 90 degree air in mojove desert in the summer. Ooh cold air intake sounds so special
Intake without exhaust mods is useless, u can't run the intake which means mouth wide open to take air for engine then ass is tight as hell for air to get out, bigger exhaust will help get the power out
Steel so i install the injen cold air on my car, will that makes my car faster?
hahahha your so wrong its insane
And without the modified ECU, it's useless
Gentrit Hoti I mean, I get why you say he’s wrong, based on his explanation (or lack of) of how a cars 4 stroke combustion system fundamentally works... but he’s not entirely wrong in that with more air coming in PHYSICALLY, you’ll need a more breathable exhaust (better yet, something less restrictive in terms of what your car or car’s engine specific design is)...to make it work most efficiently. My GTO came with the most restrictive exhaust system I’ve ever seen it was unreal how much whp was being robbed from it lmao
Great Video once again!
did your headlights on your scat pack come able to change colors stock or is that and upgrade
Do you still have your RC cars or planes if so could you do a video of all of them thanks
you need to tune it for the actual hp advatage. one wuestion i have is does a mid muffler delete effect perfomance? i have it done to my 08 srt and at first it felt slower but sounds amazing
I wouldn't say dead even. Maybe the guy weighed more.
are you going to do any performance mods? cam, heads, headers etc.
i installed afe throthle body spacer and afe intake i feel a differece but with a hemifever tune im shure ill would get better results have you tested the throthlebody spacer before.
I’ve just seen two videos before yours and the induction system has made BHP and kw power gains.This was tested on a dyno with the same car with and without the cold air intake 🤔
Is it sad that I put a cold air intake on my v6 2015 Dodge Ram regular cab long bed, tradesmen
How about fuel economy? Do CAI's work for or against that?
You need a tune when installing CAI, otherwise it's just a waste of money. Adding more fuel at WOT (richer) and adjusting the global spark timming with a tuner will squeeze out more HP at higher RPM. I've dynoed my car with CAI without a tune and actually lost 2 HP. After tune I gained 13 HP. If your limited for money, skip the CAI and get yourself a set of underdrive pulleys but just make sure your Alternator is up to par.
A big plus to have a intake is the muffler will be louder.
Does a cold air intake make a 2020 charger gt sound better with super 10
I Keep hearing that they add HP but not much.. it says that the one in my car adds close to 16 WHP, its a Cold Air Inductions kit, on a V6 Camaro. I bought the car used, was already on it.. How can they say it gains x amount HP, but everything I see, suggest otherwise..
I agree, mods without tuning doesn't work. the engine will breath easier. but you have to tune it to take in more air.
Kool looks and sounds, that's all one will get out of a CAI upgrade on a NA vehicle. Same for most power adder vehicles until the power adder is upgraded, then a CAI upgrade would improve performance, slightly.
Paired with long tubes and straight pipe and something like a diablosport tune it would pull on stock a good bit
The only thing that increased the responsiveness and acceleration in my truck was a Magnaflow catback exhaust upgrade. My truck is loud and drives like my dad's Jag.
You posed to have a tune when you add any aftermarket part
If u ran the pipe and intake outside where the cold air when ur driving gets sucked in i would bet it would make a difference
Yo I got an 2014 AWD RT last of its kind lol I wanna do the cold air intake but I don’t crazy amount of money to spend on it I’m debating between A K&N or A Mopar one I just know the mopar one like $300 and the K&N 200 something what u think
Outstanding video....thank-you very much!
thats not really a cold air intake since its still in the engine bay, the heat sheild doesnt even do much, cold air intake filters are located usally infront of a tire in the wheel well right behind either a fog light or bumper.
So its mostly sucking in hot air from the engine bay since its not placed in a appropriate spot
i dont know but would like 20°f make a difference? the other day my iat was at 92°f. and the next morning it was at like 67°f. it felt like there was a difference. i got the mopar cai. the big blue one. lol
Yeah the colder the temps the better. Cold air is more dense = more hp
the way I understand, cold air keeps the HP, since heat lowers it. after multiple runs, times can rise , so the cold air keeps them consistent and low as they can be. isn't that about right?
The Dodge Challenger SRT Hellcat has a cold air intake through one of the inner headlights. I don't know how they did it on the Charger Hellcat
Do you recommend buying a oil catch can
I'd like to see a race video with your car and a car that doesn't have muffler delete or cold air.....maybe just a KN in a stock box
Thats not a true cold air intake. More of a short ram intake. The Bwoody intake I have in my WK1 jeep actually goes down in behind the front bumper where cool air, not HOT engine bay air is hitting it. A tune with your intake will probably decrease your 8th mile time by .2 seconds.
I agree. I'm not sure why people call these "cold" air intakes if they are drawing in the hot air of the engine from behind the radiator. Every manufacture that I know of has their tubing bringing in the air that's in front of the radiator.
They call them that because they are idiots! And I'm not being an ass or a troll here it's the absolute truth. A bunch of god damn morons that believe and repeat what corporations tell them to. It's ridiculous.
AdussFadass Yeah dude, he didn't even have a CAI. Definitely looked more like a short ram!
It is a heat shielded short ram intake. The R2C intakes (have one on my G35) have a shroud around the filter that seals to the bottom of the hood to keep hot air out. Not sure how the Charger factory set up is but on my car, it retains the factory cold air "grabber" that funnels air to the intake.
Intakes alone though aren't going to give huge gains especially on an otherwise stock car. But once you open it up on the exhaust side, you do need more air intake potential. And on OBD cars, at least an ECU reset is needed to help the computer adjust to the mods but at tune is needed to maximize them.
The best "RAM" style intakes are the one that start from the front of your car to the engine itself.. The faster you go the air is being pushed into your cars engine , which would increase power. It's all in the design too..
I wouldn't expect it to by itself but combined with other upgrades it would
ya Mighty Car Mods already tested this that cold air intakes actually drop horse power by 3 not much to notice a difference at all but they dont increase anything at all
What I've heard is a CAI, plus new headers, plus a new exhaust, with a nice tune and that's when you'll really notice change.
But that's like $3-4k which I don't have. So the stock 250 HP/TQ of the 3.5L is good enough for me lol.
Depends on where and what you buy.
It has to be closed box with that round filter! cold air comes from front of the car and it goes all over the engine bay and hot air from engine bay heats the semi-sealed area you have around that air intake
The difference lies in the amount of air that can pass through the intake, MAF size has something to do with that and when a tune is calibrated to work with the intake it adds more power than a stock intake box with tune.
Good vid RP.
Hello , have a question, I have a 08 charger rt, x squad car. It seems like my intake is more beefy than a regular rt , do you know of dodge makeing the squad cars with different intake than the civilian rt? And so would it even do anything if I upgraded to a mopar aftermarket intake..
siberian charger I just brought a 2008 Dodge Charger pursue and is fast as hell just like it is and I was trying to figure the same thing out that you're trying to figure out
The reason the performance is the same is due to the stock computer parameters. If you were to change the programming from a approximate 18 to 1 air fuel mixture to a 12 to 1 with an aftermarket chip you would see a big difference in horsepower. As it is from the factory you will not burn more fuel to create more power
CAI works best on turbo diesel vehicles. You also have to do the exhaust and give it some more fuel. Exhaust diameter on turbo diesel should be at least 3 inch from turbo straight to the end.
I wonder would the 0 to 60 be different with or without the CAI???
Nope we run the same times!
A very important point: each hemi will have at least a +\- 2hp difference, maybe more. That's before you start with mods. Just FYI
Agreed
Different vehicles respond differently to mods. I have a CAI on my car and while it didn't make a major improvement, it did make me quicker. Notice I said quicker, not faster. Meaning acceleration increased. The argument that CAIs do nothing is coming from people who have never had one and bandwagon into conversations, or from those who just had it on a vehicle that already had sufficient airflow so it didn't make a difference.
Facts
God I love that purple man omg
if you get a bigger throttle body and cold air intake it makes hp increase not by alot around maybe 7 to 8
How heavy is each driver?
A dyno would have been a better accurate test as to actually driving the car
100% agree I installed the KN 69 series typhoon CAI on my scat and it threw my check engine light on and ran at crazy high temps, I ended up removing it and putting the factory intake back in with a KN performance filter from auto zone 🤷🏻♂️
Hi bud. It seems like your car was running lean with the air intake. Do you feel an Etune would have fixed that?
Short ram, not a CAI, actualy, its a bit of a Hot Air Intake...a CAI have a COLD air feed from the fendre/grill. Close that intake filter, add a cold air feed pipe and test again. And make sure you have same tire pressure, same window opening area and same number os passengers
hard to compare ;-) unless, in controlled environment with same input variables...one guy lags 500ms and it seems the other car "better".
Do a comparison between stock exhaust with Muffler vs Muffler delete
No one we know is running stock exhaust on their scat
Thanks for proving the point of air boxes don't effect speed. I did hear that it could slightly improve mpg.
Ok
they work and don't work all depends on the car and if done correctly
I wasn't wearing an infared night vision device. I totally could not see anything but lights
I thought the cold air intake sits lower so it actually grabs air from the bottom? This looks like a short ram intake.
what about fuel consumpsion??
You have a turbo?
do both cars have mid muffler delete? thinking about doing the delete on mine.
Yes they do
+RP Productions sweet thanks
If you install a CAI, wouldn't you have to adjust the fuel/air for the car to function properly? The real test is a tune on a car with CAI and a tune on the same/similar car without the CAI. Correct me if I'm wrong.
You wouldn't need a tune because there is no extra air with these intakes.
Sp 485 are you talking about the stock air intake in a shaker that looks like an after market CAI or CAI's in general? Without making adjustments after my JLT install, my car won't sound or function as well.
God Save America I'm talking about the stock intake on pretty much any modern vehicle. And I'm honestly not bring a smart ass when I say I don't understand most of what you said.. ?!?
God Save America what do you mean by adjustments? What kind of adjustments and adjustments for what exactly?
Sp 485 air fuel mixture. More air, more fuel.
In my situation I did a motor swap and couldn't find the stock air filter housing for less than $150. So i installed an intake. I had to remove my second horn to pipe it down all the way.
Idk, mines isn't chipped, I don't have more then new cats, mid pipes and an m3 exhaust, and I guess I'm comparing it to a filter literally hanging right off the MaF, but I noticed smoother idle, amd more power over 5k
Uhhh even with that heat shield you aren't pulling in cold air. Colder then previously? Sure. But I can see why you didn't see a gain. There is no room for air pressure to build up as it curves and enters your motors throttle body. Some are custom engineered for this effect.
Mines is piped all the way down. My butt Dyno predicts a 6hp increase. I had to do it. It was $40 for the kit online Vs $150 for the stock air box I
