Product Description

The K&N RC-5000 universal clamp-on oval air filter is engineered for applications where a standard reusable performance filter is required rather than a vehicle-specific model. With its large filter area and high-flow cotton gauze media, it delivers enhanced airflow and improved engine performance in custom builds, racing vehicles, generators, snowmobiles, and other non-OEM equipment.

Because this is a universal part, you must confirm fitment by measuring the intake flange size (4.75" / 121 mm inside), available height (approx. 5.625" / 143 mm) and verifying clearance around the filter housing before installation. Installation is straightforward: clamp the filter onto your intake tube, ensure a secure fit, and you're ready to go. The washable and reusable design helps reduce long-term costs and waste.
