Product Description

The K&N RX-4130-1 is a universal X-Stream clamp-on air filter with a 3-13/16" flange inner diameter in a round tapered shape. The X-Stream design adds a pleated filter element built into the top cap, increasing total filter area for higher airflow and a longer service interval compared to standard closed-top universal filters. The cotton gauze filter media is pre-oiled for outstanding filtration and low restriction right out of the box, and the ultra-strong molded pliable rubber flange absorbs vibration while allowing secure attachment to the intake tube.

The rubber flange can be stretched up to 1/16" (1.5mm) to accommodate in-between inlet sizes. Washable and reusable with K&N's cleaning and re-oiling products -- eliminating the need for disposable replacement filters and reducing landfill waste. Suitable for a wide variety of applications including racing vehicles, custom air intakes, generators, and other equipment requiring a 3-13/16" inlet clamp-on filter. Made in the USA by K&N Engineering.
