That's exactly what I was trying to say. Both the K&N's looks smaller then the better performing ones, which I would think would be part of the reason it put down smaller numbers. I know I don't buy a filter because it's the part number for my car, I go on their site, research the dimensions available, and buy the biggest one I can fit in that location.
