"All it'll do is make your engine bay look cooler and make more noise" Yes, that's exactly what I want

K&N not sending Scottie a Christmas card this year

jokes on you, I already have the check engine light on

I need that 1% HP gain Scotty…

Everytime I want to do something to my truck, scotty always says it's not a good idea. 💀

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.

Sometimes this guy knows what he's saying and sometimes he doesn't.

“You turn your car on with a key that’s bad. Car ruined” - Scotty

Up next : “Why Tires Are Bad For Your Car!”

that's why you get one that's designed for your vehicle

This guy always puts a lot of faith in engineers.

this guy disses every single mod i want

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.

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 had aftermarket intakes on just about every car I’ve ever owned. Never had a check engine light come on and I’ve always gotten better gas mileage. May not give you extra power but it does help!

Listening to this dude you’ll never have car

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.

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.

Me watching and laughing at this after having cold air intake for more than 5 years with no problems :)) But great mechanic

Just because of this video I’m about to get an cold Air intake for my 8th gen Honda Civic lol.

I installed one of these for a friend, it did turn the check engine light on, then I plugged in the mass airflow sensor, it turned it off

$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.

Scotty's casket needs a cold air intake 🤣

I love how he explains while CTS turbo, ECS tuning and apr logos are stuck under the hood 😂

Engineers might be motivated to make everything fit under the hood regardless of airflow.

Scotty is always taking the fun out of everything

Today I'm gonna tell you why owning a car is stupid. - every Scotty video ever.

I just enjoy the sound, I know it doesn’t make anything better for my particular car but I enjoy the sound enough to run with one.

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.

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.

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.

I like how it's heat wrapped with an open element design sitting in a hot engine bay. That's hilarious!

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.

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.

Your MAF sensor will compensate for the difference in airflow.

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?

People who create cold air intakes are engineers too. 😂

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

Every cold air intake manufacturer and tuners: am I a joke to you?

Next Video: Why Car Payments are Stupid... Pay cash for a 94 Celica and show everyone how Intelligent you really are.

Hot air intake

Ask any racer, and REAL racer. It doesn’t matter if you get 1hp or 100hp. Horse power is horse power

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).

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.

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.

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.

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.

I wonder how the customer feels when they see this video😂😂

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. 🤔

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.

Never seen anybody make more negative videos than this guy.

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.

Scotty: no matter what, never ever modify your car in any way whatsoever. If you do, you’re stupid.

Most cold air intakes don’t require a tune.

Actually helped my Duramax at 7200 feet above sea level.

Aren’t cold air intakes for the benefit of other stuff? Like a turbocharged or supercharged set up? Or even a nitrous set up?

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.

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.

K&N intakes don't need a tune. Literally one of the easiest upgrades for more power. K&N couldn't legally claim more power if it didn't

He's talking about a cold air intake, without even showing a cold air intake. Oh Scotty.

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.

i think it depends on what engine you have. some engines will run better with cold air intake.

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.

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.

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.

The noise alone beats all the cons for most people. It is what it is.

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.

I like the k&N filters that fit in the stock intake box.

My BMW has a cold air intake stock from the factory. The intake mods involving removing the silencer and replacing the airbox with one that can fit a big cone air filter inside of it

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

A cold air intake system will only benefit with a supporting ECU tune or "piggyback" such as the JB4 tuner, which is designed to increase boost (on turbocharged and supercharged cars) and therefore needs more air intake capability, which a higher flow intake system provides. From this, you will see more gains from the tune with an upgraded intake system, given that you have proper heat insulation and have some sort of heat wall to prevent as much heat in the engine bay being sucked into the intake.

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.

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…

“Yeah they look cool” enough said

If its in the engine compartment its still sucking hot air. It has to be in the grill on the other side of the radiator.

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...

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!

RAM air intake made a huge difference on my 2020 Nissan kicks

No a GTI can remain stock with an addition of a cold air intake. The gains are negligible, ~5hp. With a tune however, you'll gain ~10hp but tunes could push more with the help of a cold air intake. Example, my car atm has 325hp and 420 nm (309 lbft) and runs stock intake, just by adding a cold air intake, I could dial up the boost from 24.6 psi to 27-28 psi. Edit: I install a cold air intake a day after the comment. I dyno'd it again and made 350 hp (320 whp) and 472.5 nm (348 lb ft) at 28 psi of boost

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.

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.

If you measure the full torque curves, most quality intakes provide far more than 1%. More like 15%. If you're just measuring peak, then yeah, that sounds about right. Really depends on the vehicle and tuning. You definitely increase the amount of particulates allowed through.

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

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.

"the check engine light will come on" The tick in my ranger: am I a joke to you?

My dad made me buy his 2004 F150 4.6l 2 valve with the newer body, and it came with a cold air intake and loud exhaust. He told me I wouldn’t be disappointed in buying it from him for 4 grand with 140k miles when I told him I was going to buy a Silverado. After a lot of convincing I eventually gave in and bought it... I later learned that the 4.6l 2 valve is one of if not Ford’s most reliable V8 engines and they’re fairly easy to work on.

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.

When I install my cool air intake. It would be cool if Scotty roasted me. I think the cool noise and the 1.5% HP gains is worth it. Hehehe

That's a whole lot of yapping and saying nothing. Here's the deal: "If you install a cold air intake and it's near a heat source, the filter can heat soak and actually reduce your engine's horsepower. Unless you have cold air induction through a cowl hood or some sort of opening and bringing cold air to the filter, don't bother with a cold air intake." There you go scotty, I fixed it for you. Also scotty, for certain V8 engines, you can 5-10% increase in horsepower. And also, if you do tune the car, that increases horsepower also. So the 1% increase is total nonsense. We love you scotty, but sometimes you sound like a total buffoon

Cooler air is what the engine wants

What are Scotty's thoughts on washable cabin air filters, & engine air filters

Your too old Scotty just retire at this point to know what’s going on with technology

Today I’m gonna show you why driving your car everyday is bad. - Scotty probably

Ok grandpa let me work on my car know

This is one thing I disagree on. I always run a cai inside the front bumper and it helps in the summer taking intake temps from 152 to 98 degrees. My car was overheating with the stock intake.
