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. K&N filters decrease service intervals, are better flame resistant and will last much longer and breath better than comparable foam or paper type filters. 17-22 Touring; 17-22 Trikes. With OEM wedge styled air cleaner housing. We will accept your request at our earliest opportunity. This includes Republic Of Ireland.
