The K&N Drycharger is a silicone-treated polyester wrap that fits over K&N air filters and personal watercraft flame arrestors to limit water ingestion while maintaining high airflow. The wrap contains uniform micron-sized openings to preserve breathing capacity and its water-repellent treatment typically lasts one to two years. Use it as an added layer of protection where moisture exposure is a concern.
