The K&N RU-0160 is a round, straight universal clamp-on air filter built on a four-layer cotton gauze element. It is sized at a 1-1/2 inch flange, 3 inch outside diameter, and 4 inch height. Its molded rubber flange is designed to absorb vibration and hold a secure seal on the intake, and the manufacturer notes it can stretch up to 1/16 inch to bridge in-between sizes. K&N markets this high-flow filter for racing vehicles, radio-controlled cars, generators, snowmobiles, tractors, and other equipment with a 1.5 inch intake.
Against a disposable paper element, the appeal is the reusable design. The filter is washable and reusable, so the upfront cost is spread over many cleanings, and the manufacturer rates its overall efficiency at up to 99%. After each wash, the manufacturer's listed re-oiling amount is 0.29 oz (9 ml) of K&N filter oil. Because this is a universal part, measure your intake flange and the clearance around the 4 inch height before ordering a 1-1/2 inch flange air filter for a track, off-road, or utility build. Search terms like "washable 1.5 inch flange air filter," "round straight universal air filter 3 inch OD," and "K&N RU-0160 install" lead to this exact part.
