I just got a great deal on a polished AEM CAI minus the filter. Just wondering what K&N filter is the proper one to use with this. Also are there any other good compatible filters??

If I get a chance to take mine off, I'll measure it and then you can find the K&N equiv. at http://www.knfilters.com/universal/universal.htm

AEM MAkes 2.5 inch OD intake plumbing for some odd reason when the industry sandard is 3.0 OD, so a filter with a 2.5 inch opening will fit.. good luck finding one though..
