The K&N Drycharger is a silicone-treated polyester wrap made to cover K&N air filters or personal watercraft flame arrestors, allowing high airflow while limiting water intrusion. Its uniform micron-sized openings preserve breathability, and the silicone treatment improves water repellency. Typical water-repellent effectiveness lasts about one to two years depending on conditions, extending usable filter protection.
