I looked at the following K&N's before deciding on the RE-0930, based on the fact that they all have a flange with an inner diameter of 2 7/8" - 3":

RU-4730 $68.28
RR-3003 $57.48
RU-4990 $51.88
RF-1030 $44.44
RE-0930 $39.98


All prices were quoted to me by Advance Auto. I got my filter from there and it was shipped to them overnight at no cost to me or aynthing. Hope this helps.
