The K&N DryCharger RC-5112 is a silicone-treated polyester wrap made to cover K&N air filters or flame arrestors, limiting water intrusion while maintaining high airflow through uniform micron-sized openings. The water-repellent treatment typically lasts one to two years and helps protect filter media in damp or marine environments. It’s a lightweight protective pre-filter for maintaining intake performance in wet conditions.
