hey sup guys
i jus need some help for my bmw, i got a 325ci 2001. i need to kno wut products i can put in my beamer that will increase my hp, nething other then superchagers,nos,or nitro. and if u can giv me the site that'll be awesome thanks

try the ECIS cold air intake, mine helped a lot, but i had to do some customizing to get it to seal off from the engine chamber...just used some weather stripping from home depot and sealed it up good.. check it out at ecisbmw.com. also the conforti is suposedly good...evosport has them.

Intake alone won't do a whole lot... neither will and exhaust... neither will a chip/reprogram. But do all three and you can expect to see a 12-17 hp increase.
