Product Description

The K&N RU-5135 Universal Clamp-On Air Filter provides a high-quality, reusable filtration upgrade for intake systems using an approximately 2.75" (70 mm) flange. The high-flow cotton gauze media ensures improved airflow and engine performance, while the molded rubber flange absorbs vibration and ensures secure fitment.

Installation is simple: measure your intake flange to confirm it is approximately 2.75" inside-diameter, slide the RU-5135 filter over the flange, and clamp securely. As a universal-fit part, it is suitable for custom applications but not tied to a specific make, model, or year - always verify clearance and proper fitment before installation.
