It uses a RadialSeal™ gasket to create a leak-resistant, vibration-proof seal in the air cleaner housing. The high-efficiency cellulose media captures 99.9% of airborne dust and debris (ISO 5011), protecting the engine from wear. This filter is typically replaced when it becomes restricted, helping maintain fuel efficiency and engine longevity.
