Jim Reed, Longmont, Colorado
I bought a K&N filter shortly after buying my 1997 Ford F-250 deisel (new). I just replaced the filter (the rubber had a crack in it) with 225,000 miles on it. Great product and I believe it boosted power as well (although it is the only filter I have had on that truck). Now I will use the old filter if the new one needs cleaning If I don't have time to clean and re oil the other one, if i need to go somewhere. Great product.
