: : I have a K&N Drop in Filter but I don't think it's really much worth it. It helps very little on high end, slightly louder after 3500rpms, and I probably gain 1hp to the rear wheels!
: : Boston Performance Group sells ITG Drop In Filters for $36 which are much cheaper than the K&N ones.
: : Anyone else here have a ITG drop in Filter on the E36 M3?
: Has anyone put just the drop in ITG in the M? I would like to know if it has made even the slightest difference
