The K&N Drycharger wrap is a silicone-treated polyester cover made to protect K&N air filters and personal watercraft flame arrestors. Its uniform micron-sized weave permits high airflow while limiting water and contaminant entry. The water-repellent treatment typically lasts one to two years, providing added protection in wet conditions without significantly restricting breathing efficiency.
