Hi guys I'm trying to figure out some stuff about cold air intake systems I know theres a lot of crappy systems out there that claim big hp but its also big$$$.So I had an idea maybe its even something you guys mite want to try yourself.So lets get started, I have a 1990 325is mtech bmw ,I dont want to hack away at the air box I'm trying to keep the cars extiorior and interior original as possible,its black on black leather and loaded with features anyway I was thinking about making a custom ram air from an air scoop from an f150 that I had removed before I junked the truck,the scoop measures 6" wide x 1 1/2 " tall and has a round 5" tube thats a good 12'' in length total that points going up.So I was thinking of mounting it somewhere just under the lower front valance so it will be showing just a bit but not affecting the look in a bad way then I want to attach this to my stock air box inlet and add a k&n filter,does anybody think this will work Ive seen it on hotrod tv I think its a good idea??
I just bought the bavauto kit for the bracket put on a bigger K&N
save the old airbox for smog test
remove the second headlight lowbeam
then built a heat shield from sheetmetal and covered it in dynamat use pipe insulation to seal to the hood,
(closed lid on custom box is better implimentastion Ive seen)
works like a champ, wooooot...
