The K&N Drycharger is a silicone-treated polyester wrap designed to cover K&N air filters or personal watercraft flame arrestors, offering a water-repellent barrier while preserving airflow. Uniform micron-sized openings allow high air flow but limit water intrusion, and the silicone treatment typically provides water repellency for one to two years before replacement or retreatment is advisable.
