The K&N Drycharger wrap for Yamaha applications is a silicone-treated polyester cover made to protect K&N air filters or personal watercraft flame arrestors. It features uniform micron-sized openings that allow high airflow while limiting water intrusion. The Drycharger reduces water reaching the filter and is offered in black; its water-repellent treatment typically lasts one to two years under normal use.
