: : I just installed a K&N airfilter for my 323Ci.. I think I actualy felt a difference.
: : funny thing is that it was made a for a Ford e150 van.. but fits PERFACTLY.. (I checked for a Gap if there is any, but to be honest the oiled rubber seals a lot better) cost me like some $40.00
: : Well worth it.. Pre oiled and a lot thinner then the one that was in there.. good upgrade..
: : later
: : eaton
: Is it an open or boxed filter, and does installing the intake void any warranties?
