The K&N Drycharger is a silicone-treated polyester wrap made to cover K&N air filters or personal watercraft flame arrestors, offering rain and spray resistance without overly restricting airflow. Its uniform micron-sized openings allow high airflow while limiting water intrusion. The black Drycharger is a reusable pre-filter option; the water-repellent treatment typically lasts one to two years under normal use.
