I'm a newbie to this forum and am just beginning to mod the wifes '99 332I. I was told that a cold air intake should make a big difference in power. Is this true and also what brands would you guys recommend with the most bang for the buck? Also need to know if it will prevent me from clearing smog in Cali. I'll appreciate any input/advice you guys can offer. We have all the options except the power that I'm accustom to.
There are numerious types of intakes out there. Thier gains are different for each, but you won't get enourmous amounts of HP and torque out of them. Some say you'll only get about 10hp maybe just over 15hp for the 3 series BMW's, if you have an M3... a little more, a 5 series, even more.... though I am by no means an expert, but have read much about what others have said about intakes in this forum. Here are some intakes that I'm looking into:
a good start is always a K&N filter...they do real good work but if your looking for the best go for a gruppe M, they are expensive but worth it from what ive heard...
i have a cone filter from K&N for about 80$ and i noticed a great difference in power...well okey not like a turbo or something but it was noticebl...
they also give your engine a better response time...which means when u push the pedal it will react quicker

I could be wrong, of course, I am not an expert, nor am I a mechanic, I never claimed to be, however, when coupled with a "chip", gains are much greater than alone. An intake alone could produce the range in HP you mentioned, somewheres from 3 to 5 HP, however, when a Shark Injector is added, there's more HP taken from the advantage....
But of course, it would help if others verified this....
