The K&N Drycharger wrap is a silicone‑treated polyester pre‑filter that slips over K&N air filters or personal watercraft flame arrestors to limit water ingestion while preserving high airflow. Uniform micron‑sized openings allow unrestricted air passage while the treated fabric repels moisture. The water‑repellent treatment typically lasts one to two years under normal use, extending filter service life without sacrificing flow.
