Description

The K&N RU-4480 is a universal clamp-on air filter engineered for a broad spectrum of applications, including racing vehicles, generators, snowmobiles, and tractors. Its design accommodates various air intake angles and offset diameters, making it a versatile filtration solution. Constructed with ultra-strong molded pliable rubber flanges, this air filter ensures secure attachment and vibration absorption. The flanges are designed to be pliable and can be stretched up to 1/16 of an inch (1.5mm) to accommodate slightly varying intake sizes. The filter itself is washable and reusable, offering long-term value and reduced waste. With outer dimensions of 4.0625 inches, a height of 2.1875 inches, and a flange diameter of 0.75 inches, the RU-4480 is suitable for numerous setups. K&N's commitment to high airflow with excellent filtration aims to increase horsepower and acceleration for your equipment.
