The K&N Universal Air Filter with a 6-inch flange, 7.5-inch base diameter, 4.5-inch top diameter, and 4-inch height is engineered to deliver top-tier filtration and airflow for a wide range of applications. Designed for everything from high-performance racing vehicles and snowmobiles to generators and agricultural equipment, this filter adapts seamlessly to varied intake angles and offset diameters. Constructed with ultra-strong molded pliable rubber flanges, it effectively absorbs vibration while providing a secure, stretchable fit—up to 1/16 inch (1.5mm)—to accommodate in-between sizes. Washable and reusable, this K&N filter maximizes engine protection while minimizing maintenance costs.
Built for durability and versatility, the K&N Universal Air Filter ensures superior dirt-trapping capabilities without sacrificing airflow. Its easy-to-clean design means it performs season after season, making it an essential upgrade for enthusiasts and professionals who demand consistent engine performance and longevity across diverse equipment.
