Product Description

The K&N RU-4260 Universal Clamp-On Air Filter offers a flexible upgrade for custom intake systems, performance vehicles, and non-stock configurations. With an approx. 4.5" (114 mm) inside-diameter flange, this filter is built to fit a broad range of applications - car, truck, ATV, generator or other equipment requiring a clamp-on filter. Featuring high-flow washable cotton gauze media and a molded rubber flange for vibration absorption and secure fitment, it is engineered for durable performance and improved airflow.

Installation is straightforward: measure your intake pipe to ensure you have an inside-diameter flange of approx. 4.5", slide the RU-4260 filter onto the flange, clamp securely, and you're ready. The washable and reusable design means lower long-term cost versus disposable filters and a reduced environmental footprint. Because this is a universal fit part (not tied to a specific make/model/year), verify clearance and correct fitment in your engine bay or intake layout before purchase.
