Product Description

Upgrade your intake system with the K&N RU-5283HBK Universal Clamp-On Air Filter. Designed for any intake where the flange measures roughly 4.5" (114 mm) inside diameter, this high-capacity filter offers a tall 8.0" (203 mm) height and a large 8.0" (203 mm) base diameter to accommodate high-volume airflow in performance or custom applications.

Installation is straightforward: measure your intake pipe to ensure the flange is approximately 4.5" inside diameter, then slide the RU-5283HBK filter over the flange and clamp securely. Because this is a universal-fit part (not tied to a specific make/model/year vehicle), always verify clearance, intake-pipe size and overall fitment in your setup before installation. The washable, reusable design makes it a long-term value and reduces ongoing replacement costs.
