The K&N DryCharger RC-2690 is a silicone-treated polyester pre-filter wrap designed to cover K&N air filters or flame arrestors and limit water intrusion while allowing high airflow through uniform micron-sized openings. Its water-repellent treatment typically lasts one to two years, helping protect filter media in damp operating conditions without significantly restricting intake breathing or requiring filter modification for fitment.
