Hey guys,

I'm new to all this stuff and was looking to get a cold air intake for my 2004 325ci. I'm looking to get a nicer sound (rather than the electronic motor sound) and a small HP increase. Is a K&N the best way to go with this? If so, does anyone have a part number or suggested model?

Also, I'm still under warranty until November, is it risky that I'm doing this before the warranty ends? My BMW dealer said I could replace the filter, but I didn't ask them about the intake.

I have the AFE Powerflow intake w/ aluminum heat shield and it really added some nice intake snarl and noticeably made the engine punchier and more responsive
