K&N is the world-wide standard in high-end quality performance air filtering systems. Made from multiple layers of pre-oiled woven cotton gauze material that is mesh screen protected. They are washable and can be used as stock replacement. Filter elements are designed with a ribbed surface that will give you up to 5 times more filter area than a regular replacement filter, dramatically increasing airflow.
