WHY PAPER INSTEAD OF OILED GAUZE (K&N AND OTHERS)?
Dry paper is the best filter media available for protecting your engine. Oiled gauze style filters do flow a lot of air because they are very porous until they get dirty. K&N’s own test data shows lower initial pass dust retention than paper and must get dirty until they match paper’s retention. So how are you supposed to protect your engine until they get dirty? Plus, putting a replacement filter in your stock air box has not solved the design problems of the stock box; it still leaks and is small. The tractors that built the freeway you drove here on don’t use oiled gauze to protect their investment, why should you settle for less?
