Scotty, first of all if you install a cold air intake, you have to disconnect the battery cable before you install it so you don't get a check engine light. Second, they can improve fuel mileage.
@@jewsrbad That's because you're not using the heat shield that came with the cold air intake.
@@jewsrbad idk what that means
@@seangowan7441 Not really the same with a blow off valve they push on the gas just to hear the noise.
@@emerymayoros9217 in my experience it's MAF run cars that don't benefit
Any car running air temp sensor and MAP sensor instead of MAF will benefit
This is only providing that the ECU sensors stay in the original place the cold air filter will only help if it's in its own cabin and far better connecting this to the original location for cold air feed from the manufacturer
They don't build the car to recycle the warm air from the engine
So don't do this yourself
Oil the filter regularly 👍🌞👍

🤣🤣 I feel it bro
I saw a guy install one on his Volvo and he lost power because it was mounted against the hot radiator. I guess it was technically a hot air intake for him.
😂
Congratulations you played yourself. 😂
Better fuel economy tho
@@yeh.80 Nope. It was improperly installed so it was sucking in warm air. Even if it's installed correctly, cold air intakes dont always equal better fuel economy because the computer had to compensate for the increase in air volume by adding extra fuel. Aside from a software tune and weight reduction there really isn't much you can do. Most vehicles come as efficient as they can be.
Good for mpg though 😂
“You turn your car on with a key that’s bad. Car ruined” - Scotty
Thats why they invented buttons
😂😂😂😂
Sometimes this guy knows what he's saying and sometimes he doesn't.
he is correct, that adding one with no tune is bad, but with a tune it’s good
Oftentimes it's the latter.
Some CAI are dyno proven to give small increases. It a simple fact that some factory air boxes choke the car in comparison to aftermarket. Obviously not every car this will be the case.
@@megazuccc depends the car tbh some cars still gain some hp without a tune.
*most of the time he doesn't
that's why you get one that's designed for your vehicle
Its hard to get them for cars that arent really common like my alfa romeo 145 1.9jtd from 2000.Its so incommon i cant even find factory body parts
@@silentscream1871 really? Kias are like non existent in the car scene yet I found a cold air intake specifically for my Kia
@@silentscream1871 have you tried forums?
Designed to fit yes.
True. Nissan Nismo has vehicle specific modification part’s designed to enhance performance. They even give helpful tips if you do choose to tune, but they say it’s optional.
Correctly installed Cold air intakes work great, the longer the pipe is and lower to ambiant air the benefit is realized. The trouble comes when you use short ram intakes they cause issues with heat and incorrect air metering which throw cel's.
The longer pipe gets heated up from the engine compartment. Warming the air as it travels down the pipe. Negating the use of the cold air system. Like he said, little increase of any at all. The louder intake sound makes you feel like its faster. They know that they're doing selling these things.
@@rchydrozz751 you won’t get any power from any bolt-on without a tune. The tune on my car throws an engine code with a stock air box. It doesn’t pull in enough air.
@@thatsmyassbrostop Wrong wrong wrong. It HIGHLY depends on the car. Some cars can take simple modifications and the ECU adapts. With a tune you 99.9% of the time gain significant power.
@@unforeseen9267 it of course matters on the car but the majority of the time you’ll likely see a performance drop without a tune. I would have to see some solid numbers to believe that any modern car can get higher than negligible gains without a change to ECU. In basically every application you’re just going to run lean, though I’m sure some exceptions exist.

@@luweewee Scotty isn’t god. And if you’ve ever been a mechanic you know that those engineers often aren’t gods either.
I always loved how people would remove the airbox that actually sucked air from outside and replaced it with a "cold air" cone filter sitting in the hot engine bay. Real men of genius!
I’ve seen plenty of Honda’s on OfferUp with an aftermarket intake pipe but with no filter at all
I removed my airbox and tuned my car with the cold air intake. Closed box intake but it sounds beautiful. Definitely worth it if you like the sounds but tune your car first!!
I believe the purpose of cold air intakes is to make your vehicle louder, not faster.

LOL!!! 💯💯
You must be one of those that got offended by this video 😂
Just FYI, most engines have adaptive tuning, based on the air to fuel ratio, which get altered when doing a CAI, the ECU adjust as needed by itself.
This couldnt be more false. Many modern engines have parameters in the ECU which pertain to MAF scaling and the size of the intake tubing. When you change the diameter of the piping that the MAF sits in but dont change the scaling in the ECU, you change the Grams per second airflow which will effect the engines ability to properly calculate fuel injector duty cycles from idle to redline. This means that lean at idle is extremely lean at redline, and lean is a good way to induce knock, and burns holes in pistons due to excessive heat.
The ecu can only correct so much until it maxes out certain values and then it gives up and turns the check engine light on. This could be triggered from anything from a high or low voltage/current or performance error for the MAF sensor or a correlation between MAF and MAP readings. This could also trigger a rich or lean code for the A/F ratio sensor due to the extra airflow that the ecu cant compensate for.
Blanket statements are dangerous when it comes to things like this.
@@justindelvalle9179 I’ve had a K&N CAI on my 2012 Honda Accord for over two years now. You wouldn’t believe what I’ve put that car through, and it has never had a single engine issue. Granted, it’s well-maintained, but still. Not one issue. Not all cars are the same, but you telling me what my car could do doesn’t mean jack.
@@peterpumpkineater5927 im not going to sit here and argue with someone who clearly doesnt care. But I bet you if I hooked a wideband Sensor up to it, and datalog it, guarantee your engine is running lean and likely pulling timing as well. Sorry but from a tuning standpoint you dont have a leg to stand on. Yes YOU may not have had any issues because its within what the ecu parameters can correct for but not ALL cars are like this. And after tuning enough shitbox Hondas, i have seen the vast majority of CAI run lean above 3k rpm and pull timing.
@@justindelvalle9179 Well said brother 👌
You have no idea what you are on about
From my experience true cold air intake goes all the way down to where the bumper is that way there’s no heat soak and should be made out of plastic or silicone to keep heat off. They also sell water cover mesh that you put around the filter to keep it from getting soaked and who ever is dumb enough to sit their car on a deep puddle/flood or drive through a flood where their filter emerges in shouldn’t be modifying their car.
Yup,how i have mines
Ever heard about hydro lock?
The air still heats up. As soon as it enters engine bay. Silicone is the way. But still heats up.
@@michalbiajgo3778 ever seen life OD shove a garden hose at full blast down the intake while it's running and get no hydrolock
this is in fact wrong any aftermarket intake in which opens up and make sure intake more free also usually rolling to somewhere with a cooler air source or flow a lot of vehicles stay away from the front wheel wells so you don’t Hydro like your motor because those mesh socks don’t work too well
$400 K&N cold air intake was great on my 5.7L sequoia for almost 20k miles.
Then it threw codes and ran lean.
Paid $500 to two Toyota master techs to diagnose. They checked the entire fuel line, plugs, engine, etc.
It was the cold air intake. Sold it to someone and put oem back on. No issues the last two years and 17k miles.
Also does nothing for mpg. Just makes nice sound. That’s all.
Just because of this video I’m about to get an cold Air intake for my 8th gen Honda Civic lol.
Do it! Got one on mine and the extra hamsters under the hood really scream
@@scooterbobscout I'm thinking bout getting the one where the intake sits near the battery area is thst good. It has a heat shield on the sides

I was wondering if you got better MPG with the cold air intake?
@@SebastianHernandez-wm8he more air in, more fuel in, less mpg but more power.
Today I'm gonna tell you why owning a car is stupid. - every Scotty video ever.
‘They look cool and they make more noice’. Scotty I’m sold!
Engineers might be motivated to make everything fit under the hood regardless of airflow.
Or stay within a budget.
@@thatsmyassbrostop or make it more restrictive due to certain states having strict laws
@@g00ber24 sometimes it being restrictive is due to using cheap plastic parts that are designed to “just work” but not work the best.
Well, I had a mk5 VW GTI like the one in this video from 2006-2020. I brought it in to the dealership for my first free oil change. When the service dude pulled off the engine cover he broke it at the rear left grommet and didn't tell me. The mk5 GTI is a really good car but there is one major design flaw - the air filter is part of the engine cover and the air passes through it! I didn't know it had a hole until I took it off when I changed my spark plugs. By then the warranty had expired. Turns out the leak messed up the air system making the car jumpy. When I replaced the engine cover it drove a lot better. Because of its multiple parts, a new mk5 GTI engine cover is $350. So I went to ebay and a kid who bought one of the those cold air intakes no longer needed his stock engine cover and I bought it for $35 plus shipping. So cold air intakes are good for one thing - devaluing stock engine covers. Because of that experience I stopped going to dealerships, even for the free service, and do it myself with one exception. I got a new car and the stereo screen blacked out. The stereo still worked but you couldn't control it. The dealer replaced the screen under warranty.
Scotty's assuming I wasn't already going to tune my shot box anyway
I put one on my 2013 Accord EX-L V6, and it made a very noticeable difference. On takeoff, my tires now bark going into 2nd. Acceleration is definitely improved, and it sounds amazing for the price.

And thats all that matters
I like how it's heat wrapped with an open element design sitting in a hot engine bay. That's hilarious!
Guess they forgot to wrap (insulate) that filter too lol 🤗
@@Gleeleeglee Right? LOL
LMAO...next will be a rear wing added...lol
Ummm it’s literally right and above in front of 2 air ducts coming into the engine bay. It’s sucking in the same air that the airbox does it just isn’t as restrictive.
@@thatsmyassbrostop it can't "suck" anymore because there used to be a sealed box there that could allow it to "suck" air from outside.
What you just said, is the type of person to believe that this wrap on the air pipe is helping. When you remove the air box, it can't draw air from outside anymore because the open air filter is drawing from every direction. Those tubes your talking about is designed for a closed box system, they don't work by forced air into it while driving.
Just stop dude. No.
Got a k&n intake, feels fantastic! Louder yes absolutely however, definitely feels like my power is transferred consistently if not better during hard pulls😍mopar life
Better throttle response is usually the most noticed from a better flowing intake. Car can grab that air a lot quicker and more efficiently with a well designed aftermarket intake
Hell yeah
I added a cold air intake to my 2003 Dodge Ram 1500 with the 4.7L Magnum V8. The mileage improved and I gained noticeable power when my truck was in fifth gear (overdrive).
Scotty I have one that is bolt on for the same distance, I literally have it on a Lexus nx 200t 2015, it's been on for 125,000 miles. I have literally zero issues with it but again mine is AEM bolt on vehicle specific. I get better gas mileage and I get more hp. I'm sorry but on a turbo engine I feel it's a necessity.
I been looking for an injen one and I found it and it’s a bolt on fitted for my specific vehicle you think I’ll be good ? It’s not AEM but I know Injen is good quality too
But can't you just get an CAI that allows you to put your airflow sensor on it and the ecu will adjust the fuel ratio?
Yes. As long as it has a port to relocate the mass af sensor on a modern car, then typically your ecu can adjust for it. The sensor just needs to have a couple inches of straight airflow before the air hits it.. I know mine (2016 accord v6) did just fine when I put a SRI on it. I still did a flash tune soon after, but otherwise it was running fine. No appreciable loss in power with just an intake. Sounds amazing though lol.
People who create cold air intakes are engineers too. 😂
Every cold air intake manufacturer and tuners: am I a joke to you?
No the manufacturers put the original air intake on to Maximize comfort. While putting a cold air intake on it will alow the engine to breathe so it will be louder but it’s also some what better for the engine. One way to think about is like trying to breathe with a mask on compared to without a mask.
Hot air intake
But in the case of VWs if it has a turbo it gets hot in the turbo anyways then Gets cooled back down in the intercooler
Your MAF sensor will compensate for the difference in airflow.
Sensor? Compensate? Sensor only can sense and send data to the computer. No?
@@mrbubbles6961 and then the computer would tell your injectors to squirt more boom juice. No?
@@lanceruscoe5228 so injectors will compensate. No?
Computer will compensate. Yes.
Nah. Your computer has to be told to and the MAF will comply with the new settings. Doing this without a tune could actually cause a MAF sensor to fail.
If the manufacturer offeres it as an upgrade they also designed the intake system to work with it. Just get the oem or one that is very similar
To each their own, I put a aftermarket intake on my truck I can tell it gained a little power (maybe 20hp) and mpg (maybe 5 more miles a gallon) since the engine isn’t having to work as hard to pull in air. And no check engine lights come on because it uses the original maf sensors. A heat shield keeps the hot air away from my cone filter just like the original box did.
I like the k&N filters that fit in the stock intake box.
I put a knock off K&N in my mazda 6. Then kept putting back in the ordinal stuff. Did it 5 times and made sure to record mileage and made sure time engine ran and sure that matched on a MPG basis. Kept track starting with a full tank to empty each time and did it when I knew my driving route would be identical and drove the same way. Consistently had a 5-6 MPG increase. With stop and go traffic it might have been less or worse, my driving was 80-90% on cruise control at 60 and 65. Was getting 33mpg instead of 27-28mpg. I think Mazda listed it as 30mpg on highway.
I was told to make sure I disconnect the battery for at least 10 minutes when I switched air intake. I believe it had to do with it causing the MAS to reset itself. Idk if that mattered but that's what I did🤷🏿♂️. Also have no idea if power was increased, didn't care. Only got it for gas mileage.
This dude is one of the car guys that likes everything in its original state so he spits out trash against what he doesn't understand. I installed a cold air intake in my 5.7 Hemi and gained 23 hp on the dyno before I even upgraded my throttle body. Literally almost even part on a car he says not to change, I have done and my car's been running in tip top shape for 4 years now.
"the check engine light will come on"
The tick in my ranger: am I a joke to you?
CAI works well on my ram pickup. Draws air from behind my front bumper that sits 2 feet off the ground. Gave me a slight increase in fuel economy, Lowered my air intake temps,no vaporlock and no codes. All this before I tuned it. I thought it out before installing it. Just do your research before slapping parts on it and you should be fine.
Scotty Kilmer, the kind of guy to tell you need back pressure on a 4 stroke engine.
These are the same “engineers” who decided to put starters underneath the intake manifold. 🤔
Aka Cadillac Northstar… smh. Where’s my starter? Oh under the intake roasting between the heads… thanks brilliant engineers.
Cold air were good back the the good old days when cars were really restricted from the factory. Now days it's all looks and if you want one that is proven horsepower it'll cost you alot of money. After market tuners spent countless years testing their products to make power at a certain speed or rpm. Like Scott days sheap intake China made from eBay might actually decrease power and performance. Coming from a guy who spent alot of money testing intake kits from various high end Japanese companies like HKS, Blitz, Apex, Greedy etc.
What brand should I use?
I mean a cheap K&N filter brought the mileage from an old 5.9 durango from 14 to 16 just cause it could actually breath
@@gregoryrose13👍
Greedy lol no kidding there, if i see the greedy or trust emblem on a part I know its going to be double the price of a domestic made part.
K&N filters let more dirt into your car (versus stock). Been proved bu comparison studies
I have a very similar model mk5 GTI. I spent a week with different types of cold air piping, short and long set ups, in the end the factory box worked best.
Ask any racer, and REAL racer. It doesn’t matter if you get 1hp or 100hp. Horse power is horse power
Most cold air intakes don’t require a tune.
Exactly they are plug and play
Yep. I've seen several videos of people just swapping the old one for the cold air intake. It's not that hard to do.

I got a stage 2 tune on my tdi. I put a kerma CAI and smooth elbow on and it has made a big difference in intake temp and exhaust temp. Makes a big difference in the southwest desert. My fuel consumption has changed. I'm getting better mileage. So I'm happy.
people love to go crazy for that 1-1 1/2 extra hp & louder noise & cool looking engine bay
Bruh is a voice actor trapped in a car expert
Scotty: no matter what, never ever modify your car in any way whatsoever. If you do, you’re stupid.
Yes he says stupid, should say silly mods instead. If you put an upgraded braking kit , or sports suspensions that is not silly for me. But this CAI....
Ignoring the fact that many ECUs self learn, so a cold air intake will actually be beneficial if installed correctly. Engineers designed the original intake system to meet noise regulations, emissions regulations, and cost restrictions. Providing they are thought out and installed properly they will make a positive difference, even if it may not be measurable.
ECU's self-learn for adjusting back to desired parameters, not making improvements. You need a tune to see gains from a radically different intake setup.
Yeah they pull time
I owned a 2007 VW GTi and Ill admit the cold air intake made a massive difference with the BPY engine. That engine used an air box built into the engine cover. Filter was a pain to replace.
The low end torque benefits most with that particular engine and was a requirement for the APR tune that I had flashed to the ECU.
Now I cant disagree that CAI are good in every application but I cannot agree that all CAI applications are not beneficial. Thanks for the video.
More noise plus 0.5 HP?! Please, you had me at more noise!
The intake in the video is actually no good. It doesn't isolate the intake from the engine compartment heat. Most modern cars already have a cold air source. The air is taken from the fender or right beside the radiator, from the factory.
its actually an effing bad er..... sorry, STUPID.... design.... just imagine using a metal pipe INSIDE the engine bay to transfer already hot air into the intake where the original used ABS plastic that does not conduct heat and the intake is taken from OUTSIDE the engine bay and is insulated from the engine bay heat.
@@jonasmartinez1739 Its weird that he did not even notice its a hot air intake.
When you have high flow exhast and better injectors paired with a cold air intake will gain horsepower and torque if you get a quality intake that has a proper air dam.
Had one on the same gen VW shown here . Loved the way it made it sound. Never had an issue with it !
I added one onto my 14 Ford Taurus with the 3.5L naturally aspirated engine. I also changed the grille to allow more air flow. Guess what? No check engine light, my gas mileage increased, and has better response with zero tuning. Amazing! Now I will admit my experience isn't typical for everyone but I am happy with mine.
I see them sometimes on Jeeps and other off-road vehicles. The K&N filters don't filter out dust as well as OEM, they allow water into the engine easier than OEM, and you never use full throttle when off-roading anyway. Just stupid.
Bunch of momos
Well said, just proves if you advertise enough people will fall for the garbage.
Whats stupid is how i wasted over $70 bucks on a k&n air filter itself
I wonder how the customer feels when they see this video😂😂
I feel the same! Put a K&N on my Mustang. Never had to touch my engine adjustments. Made the engine have a deeper growl and louder too! Not sure if everyone will get the same outcome though.
Probably running a tune and Scotty didn’t know so their air intake is probably totally functional.
RAM air intake made a huge difference on my 2020 Nissan kicks
I know nothing about cars and I watch this channel because Scotty knows everything about cars and is a righteous dude and makes me laugh.
Scotty those are not cold air intakes.. these are normal instakes without any housing for fresh air coming into them, instead the one your showing soaks up lots of engine heat.. a proper cold air intake would be air filter housed in a container and then fresh air feed from the outside into the air intake.. like how manufactures design them... when you buy the car.. sometimes the manufacture design is the best...
My nieces daughter has a little Scion that she bought already modified. It was done real well and was a little hotrod until last week. Her father drove it through a puddle. The combination of the cold air intake and the plastic panel underneath having been knocked off in a earlier interstate highway debris strike sealed the engines fate. It doesn't take much water to destroy a engine.
Laughs in BMW, cold air intake, charge pipe, tune on my cell phone...
But Scottie I have tuning software and I tune my vehicle when I put new parts on it. When you do an intake you also turn off torque management and increase timing and fatten the fuel to a Better power ratio. Then that intake nets you quite a lot of power. Especially when you pair it with a cam or other mods…
Ah yes I'll just pick up and plug in my new cam when I go to AutoZone and buy a cold air intake. Bro he's not saying cold air intakes never work, he's saying if it's the only mod and it's not done right it's stupid
I put a short ram intake on my car because the factory one was picking up the air from 4" off the ground and I drive in a city that gets 18" deep puddles. It has already saved me from hydro locking my engine at least once.
Bro u u just killed my vibe
Scotty agreeing it will make more noise and look cool makes me want one even more now thanks lol
He's talking about a cold air intake, without even showing a cold air intake. Oh Scotty.
Most newish cars tune themselves, you have maf/map sensors to tell your engine how much air it allows it’s self to run on
how new we talking cause i just ordered one and scottys ruinin all my fun 😂
@@maxolla6114probably any cars with an OBD II port that throws codes which is cars after 1996
This is true! Disconnect your battery for like 10 minutes, this will help reset the computer, just note that your car may seem like it’s having slight problems on start up, but it’s the computer re learning it’s engine, this will improve over time as it tunes itself
i think it depends on what engine you have. some engines will run better with cold air intake.
The noise alone beats all the cons for most people. It is what it is.
The oil on my KnN was getting on the maf sensor. Had to clean it every once in a while. They might not give much hp. But throttle response might be improved.
So correct Scotty. The air intake system needs to tuned how the engine so intake pulse of one cylinder will not screw up on another cylinder.
Ok grandpa let me work on my car know
Scotty, you didn't bring up the fact that stock intakes have resonator tubes and/or boxes that are specifically tuned lengths and volumes to take advantage of flow reverberation caused by the intake valves closing, producing more power and efficiency through scavenging than even no intake tube and filter at all. Every time I've removed a stock intake for something else on an otherwise stock engine, it caused a loss of power as well as economy. The engineers with huge R+D budgets do actually know what their doing. Power and economy are hugely competitive between brands. They are, in fact, incentivized to maximize power and economy (huge selling points). A stock intake will never be a restriction on a stock engine (they have no reason to do that). Without a full exhaust AND a cam change to take advantage of it, there really is no need to change the intake duct. On an internally stock engine, you can't do better than the stock one. The stock ones from every single manufacturer have been pulling real cold air (isolated completely from the engine bay) from the factory since the 80s, lol. You DO NOT want to get rid of the factory resonator setup in the intake under any circumstances..... unless you have a heavily modified (internally) engine and a proper dyno tune to match.
Never seen anybody make more negative videos than this guy.
I actually put a cold air intake on my 05 Ford Focus with 183,000 at the time and replaced the "lifetime air filter". I had no check engine lights regarding air flow after the replacement and I did not get it tuned. I figured it was cheaper to do that than buying a new one. Plus the car was turning into junk anyways and the transmission was starting to slip. Not saying that this will work for everyone, but it did help in my case.
Me too!
How did you know it actually helped?
@@Gleeleeglee because as soon as I put that in I could hear the car run better. The lifetime air filter had never been replaced before in that vehicle. The car also had some extra power it didn't have before.
The CEL can be that your car is not used to a lot air at specific rpms. For my camry at idle it doesn’t pull in much air so it’s tuned for low air flow from factory. Putting an intake on will increase that air and might exceed what the maf can read. It’s not that it can’t read it you either need a tune so the maf can read it or place an insert to avoid getting a CEL. At higher speeds there’s no issue.
I mean that at idle if everything is tuned for low air flow then having high air flow at idle may set off CEL without a tune. Yes you can gain HP without a tune.
Had my CAI on for a few months now with no tune and bone stock and I'm satisfied. I also got it for this summer so i can keep my engine cooler. My car does run better also. Most modern day cars won't get a check engine light just for a simple CAI, mine has never came on once.
Scotty you are missing an important point ,cold air intakes are “Very” useful if they are Ducted correctly and flow is controlled , same with and “Exhaust system” I agree 100% with tuning any engine that has been modified any sort of way
most modern cars now come with a factory installed cold air intake... and it was designed by engineers for the cars it was installed in.... I cant see your point regarding intakes being tuned because the factory cold air from volkwagen was designed and tuned by engineers, not boys in baggy pants who just happened to know what a dynamometer is.
@@jonasmartinez1739 cold air intakes work in conjunction with other modifications. That's when horse power is increased. Cars from the factory are usually not tuned for performance, that is why performance cars usually require to be tuned, to squeeze out extra horses.
@jonas Martinez is repeating what Scotty Kilmer already said because he’s watched every video and now he is an expert in tuning a engine lol.. maybe try to go actually educate yourself about engines before saying something stupid about baggy pants which has nothing to do with engines LOL
K&N engineering tunes the cold air intake to your vehicle, not the vehicle to the cold air intake. They also come with a heat shield to keep the heat from the engine from getting sucked in to the intake. You also have to remove or cut out a panel in a specific area to allow the fresh air to come in to the intake tube. Yes there are cheap cold air intakes out there but K&N isn't cheap, it's legit!
Planning to "rebuild" my SAAB 9-3 AERO back to the original air filter as the previous owners put one of those airfilters on.
I installed a kandn cold air intake on my 2016 Honda accord sport 2.4L when I bought it brand new and have had it on for over 100,000 miles, never an issue with check engine light or driving. It increased my mpg and torque at lower rpms especially with the eco leaf button on since it uses the lower power band rpm range for driving around town.
Never had an intake turn on a check engine light, and they don't necessarily have to be tuned unless it changes the Mass Air Flow sensor diameter.
