Product Description

The K&N RX-3800 Universal X-Stream Clamp-On Air Filter offers an advanced universal-fit solution for intake systems using an approx. 2.438" (62 mm) inside-diameter flange. With the X-Stream top design adding additional media surface area, this filter is engineered for higher airflow, improved engine breathing, and extended service intervals.

Installation is straightforward: measure your intake flange to confirm roughly 2.438" inside diameter, slide the RX-3800 filter onto the flange, clamp securely, and you're ready. Because it is a universal-fit part (not tied to a specific make/model/year), always verify clearance and correct flange compatibility in your intake system before installation.
