[snakeviper360]

how can i add power to my 2004 325ci it has around 48 k on it and it is stock is there anyway i can boost the stock HP by like an extra 20 more horses the cheaper way is nice because i am only 18 and paying for it on my own.

and also is it normal for your car to misfire once in a while because when i try turning on my car rarely it takes a little longer to ignite.. is there anything wrong with my 2004 BMW 325ci and its not the battery just a heads up

There's just no way to cheaply boost the hp. They are pretty well tuned from the factory to squeeze out all hp without added cost. A GOOD cold air intake made for a BMW (not some generic crap) and a performance exhaust might get you 7 - 15 hp more max, at a cost of $500 - $1000. Beyond that it gets even more expensive...

Hi guys, new to the forum so please go easy on me. If I go with the CAI upgrade which would you guys recommend aFe or K&N? Thanks

I would get the K&N, you can get here for $100.00 less than the AFE at Bav Auto or BMP Design.
