cold air...

[polizei144]

scrounged enough money for my first mod to my 328ci. ive decided to go with a cold air intake. i am willing to spend $250 not counting shipping. just wondering which has the most bang for your buck... most hp gain and best sound. thanks in advance!

Bang for the buck? From what I have read on DIY sites, you will find that it sounds a bit louder and revs just a bit more freely if you simply remove the baffle from the air box. Total investment $0, and legal in all 50 states.

I suspect the claims made by the cold air intake kits, even the ones that appear to be intelligently designed.

I suggest that you not simply remove the air box and replace it with an oiled cloth or oiled foam filter. That is the worst of all possible intake options.

Afterthought - Oops, just realized that this is the e46 forum, not the e36 (I have both models and visit both forums). I am not sure there is a removable baffle in the e46 airbox, you will have to look.

ive got a gruppe m c/f intake on my e46 328. its got more induction noise now but it didnt add much power if at all.
i even made a cold air intake up to it from a vent in the bumper.

anything short of forced inducion isnt going to reap u much power gain.
