The K&N Engineering RG-1001BL Universal Air Filter is designed for a wide range of automotive, powersports, equipment, and custom intake applications. Its chrome round tapered housing and blue filter media provide a practical solution for applications requiring a clamp-on replacement or custom air filter. The filter is suitable for racing vehicles, generators, snowmobiles, tractors, radio-controlled vehicles, and other equipment with a compatible intake.

A pliable molded rubber flange helps absorb vibration and provides a secure connection to the intake tube. The flexible flange can accommodate slight variations between intake and filter sizes, helping support a reliable fit where exact sizing is not available. The washable and reusable design allows the K&N Engineering RG-1001BL to be cleaned and returned to service rather than replaced after routine maintenance.

This universal air filter is intended for off-road, racing, custom, and other applications where fitment is verified by the installer. It is not CARB approved, and the vehicle or equipment owner is responsible for confirming compliance with applicable emissions regulations. For cleaning and maintenance, pair the filter with the K&N 99-5000 Filter Care Service Kit Aerosol. The product includes K&N's 1-year limited warranty.
