And they provide zero tangible benefit to the user.
Wanna pay more money, for more aggravation, and less quality? Buy a K&N!

After running the filter for 10 months I foud nothing gritty on the inside parts of the filter housing not even in the areas where the blow by oil condensed and would allow anything getting passed the air filter to stick on. There is a lot of dirt in the air where I live. I am not even 1/10 of a mile from a freeway that serves the Port Of Long Beach and being by the ocean and industrial area there is plenty of dirt and wind. My point is I could replace a lot of paper filters in a years time (if I did not blow them out with an air gun so I could get some more use out of them).
