I used the Fram air hog for the first 10,000 miles, did pretty well after 2 "recharges". I did notice it being a little more peppy, but I would go with the K&N. My air hog developed a rip in the rubber and it would not seal properly, got it replaced and again it ripped, same place almost. Go with the K&N, nice try Fram, it had potential but materials seem cheaper to me. Of course this is all my opinion. However I do miss it when it did work since I do notice a difference now that im back to paper filters while im waiting on my K and N
