The K&N Drycharger is a silicone-treated polyester wrap designed to cover K&N air filters or personal watercraft flame arrestors, limiting the amount of water that reaches the element while preserving high airflow through its uniform micron openings. The water-repellent treatment typically lasts one to two years, making the Drycharger a practical pre-filter for wet or marine conditions where additional moisture resistance is desired.
