The K&N Drycharger is a silicone-treated polyester wrap designed to cover K&N air filters or personal watercraft flame arrestors, sized with a 5.125in base ID, 3.5in top ID and 6in height. Uniform micron-sized openings allow high airflow while the water-repellent treatment limits water ingestion. Treatment typically lasts one to two years, offering added protection without noticeably restricting flow.
