yea that sounds kind of long, i used a filter from advanced auto..i think it is a 7" maybe smaller, i got it from the ricer section. what kind of intake are you trying to install? a homemade FWI?
how did you go about doing your fwi without removing the bumper? and what size filter did you use? i bought the long spectre filter which is 10.25" long. but has a 7" base with the 4" inlet is that to big?
