Product Description

The K&N RU-5114 Universal Clamp-On Air Filter is a high-performance universal-fit upgrade. With a flange diameter of approximately 3.5" (89 mm), it's suitable for a wide range of applications - from custom intakes and aftermarket builds to cars and trucks requiring a clamp-on filter. The washable cotton gauze media and durable molded flange make it built for both performance and long-life use.

Installation is simple: confirm your intake pipe flange is approx. 3.5" inside diameter, slide the RU-5114 onto the flange, clamp securely, and you're ready. Because this is a universal fit part (not tied to a specific make/model/year), it's ideal for custom or flexible applications - just verify clearance and fitment before purchase.
