The K&N Drycharger silicone‑treated polyester wrap in black covers K&N air filters or personal watercraft flame arrestors to limit water intrusion while permitting high airflow. Its uniform micron‑sized openings maintain breathability yet reduce the volume of water that reaches the filter. The water‑repellent treatment typically lasts one to two years between reapplications.
