Product Description

The K&N RU-4690 Universal Clamp-On Air Filter offers a reliable and flexible upgrade for intake systems that accept a ~3.0" (76 mm) flange. Designed for performance-minded drivers and custom builds, this filter features high-flow washable cotton gauze media and a robust molded rubber flange that accommodates slight variations in size while absorbing vibration.

Installation is straightforward: confirm your intake flange is approximately 3.0" (76 mm) inside diameter, slide the RU-4690 filter onto the flange, clamp securely, and you're ready. With its washable and reusable design, you'll save on replacement costs and reduce waste compared to single-use filters. As this is a universal-fit product - not tied to a specific make/model/year - please verify clearance and fitment in your engine bay or intake system before purchasing.
