Those two letters alone, K&N, are virtually synonymous with superior airflow and performance. Based in Riverside, California, K&N Engineering invented the reusable / rechargeable high flow cotton air filter back in 1969 and has been blowing the doors off anything with wheels ever since. If you want your stock bike to breathe better, run cooler and make more power, a K&N air cleaner assembly or high flow replacement air filter and a fuel tuner is typically the best place to start in terms of bang for your buck - highest performance for the lowest price! RevZilla carries a wide selection and fitment of K & N motorcycle air filters and oil filters for Harleys as well as sport bikes and dirt bikes.
