The K&N Engineering RC-5052 Universal Tapered Conical Air Filter is designed for a wide range of automotive, racing, powersports, generator, tractor, snowmobile, and radio-controlled applications. Its tapered conical design supports air intake systems with a 6.69-inch base outside diameter, 2.36-inch top outside diameter, and 4.88-inch height, making it a practical solution for custom intake installations and specialized equipment.

Built with a high-strength, pliable rubber flange, the K&N RC-5052 helps absorb vibration while providing a secure connection to the intake tube. The flexible flange can accommodate slight variations between sizes, supporting a reliable fit where intake dimensions are not exact. The washable and reusable filter media allows the filter to be cleaned and serviced rather than routinely replaced, helping simplify long-term maintenance.

The K&N Engineering RC-5052 is also compatible with the RC-5052DK Air Filter Wrap and K&N 99-5000 Filter Care Service Kit Aerosol. It is backed by a 1-year limited warranty.
