The K&N Universal PreCharger flat air filter wrap in black (7 x 7 in.) is a silicone-treated polyester cover designed to protect K&N air filters and flame arrestors while allowing high airflow through uniform micron-sized openings. It reduces the amount of water reaching the filter and offers a water-repellent treatment that typically lasts one to two years for added seasonal protection.
