Why NOT To Install A Cold Air Intake

Why NOT To Install A Cold Air Intake

Scotty Kilmer, mechanic for the last 50 years, shows why it's a dumb idea to install a cold air intake on your stock car. Kids do it all the time, but really, what do they know about engineering?

scotty what is about the use of an air filter with wet oil sump? would it not filter better? how is its comparison to paper filters w.r.t., pressure drop? and what if I use 'ram air' to increase the atm pressure?

More valuable common sense,.. hot air rises, so that's a bad spot for those anyway...and why the engineers directed the air intake low as possible, because cold air settles.

Changed it to stock and P0300 codes are gone! But... then we realized car was automatic and got switched over to standard. Got the correct ECU and now we’re pulling P0752 and P0758. There’s some electrical components dangling in the engine bay... might be that. Not sure if I’m doing this all right, but I’m trying to improve the car bit by bit.

yes, that can cause all those problems going away from stock

So I just bought a 2001 Celica GT that has an aftermarket air intake. Could this be a possible reason why I’m getting a P0300 code? My dad thought it needed a new gasket and when we pulled everything off I saw these guys circled here. I have no idea what they are supposed to be for. I’m new to all this repair stuff so I’m just trying to figure it all out. Any help would be appreciated so, so much!

I am one of those fools that put a cold air intake on my vehicle. Started having issues with acceleration, found that the oil from the filter was getting onto MAF sensor and screwing up its readings. But was able to clean with appropriate cleaner
