E90 330i Best air filter for noise
Hi Guys,
Please advise, I’m after sourcing a few servicing parts at the minute and need a new air filter, are there any replacement air panel filters , pipercross , k&n etc that I would hear an increase in induction noise from ?, or not . after reading a few previous threads I believe the stock one is good !, but I would upgrade if anyone on here has already done this and gets more noise when accelerating . Thanks |

I drilled a few holes on the unfiltered underside of my airbox on an E46 330i I used to have years ago.
