I want to like k&n, but as the saying around here goes, " why would you pour sand into your engine", anyways-
Thats why I dont like K&N. I have been using fram air filters and probably will try a purator next round.
I'll tell you what you do. Put a new paper air filter in, change the oil and oil filter and run the truck for a OCI then have a UOA done. Then install the K&N filter, change the oil and oil filter using the same exact brand/weight oil and brand/type oil filter as you used during the paper filter run. Run it for a OCI, then have another UOA done. See what the results tell you. Form your own opinion and either continue to run it or not. Simple as that. No debate needed. If the K&N sucks that bad, it will be immediately visible in the UOA.
