Product Description

The K&N RX-4730 Universal X-Stream Clamp-On Air Filter provides a high-flow, reusable upgrade for intake systems with a ~3.0" (76 mm) inside-diameter flange. Its X-Stream top design increases filter surface area for enhanced airflow, while maintaining high filtration efficiency.

Installation is simple: verify the intake pipe or mounting flange is approximately 3.0" inside diameter, slide the RX-4730 over the flange, and secure with a hose clamp. As a universal-fit part, always check clearance and compatibility before installation. The washable, reusable media reduces long-term costs and waste compared to disposable filters.
