I'm one of the "poor saps" LOL, that uses K&N air filter elements. The filters for a typical American round filter application cost around $40.In my opinion, in day , day out service, they are superior to any paper filter.They filter when wet and only need to be cleaned or reoiled once every few years.That 5 free HP increases rapidly as a paper filters restriction increases very quickly with age.Try one, you'll like it. last filter you will buy for your daily driver.
