They are washable and can be used as stock replacement. The 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. The K&N filter elements have a steel body with cotton between the screens. K&N filters decrease service intervals, are better flame resistant and will last much longer than comparable foam or paper type filters.
