K&N RU-4710 Universal Dual Flange Oval Tapered Air Filter (2.375in ID, 6.75in Height)

The K&N RU-4710 is a high-performance universal clamp-on air filter engineered to increase horsepower and acceleration by providing superior airflow with approximately 99% filtration efficiency. This unique dual-flange oval tapered design is an ideal solution for custom intake fabrication, racing vehicles, and specialized industrial equipment where space is limited and dual mounting points are required.

Built with K&N's signature four layers of pleated cotton gauze media, this filter comes pre-oiled and ready for installation. The flanges are constructed from pliable, molded black rubber designed to absorb engine vibration and provide a leak-free seal. For a precise fit, the rubber flanges can stretch up to 1/16 of an inch (1.5mm) to accommodate slight variations in intake tube diameters.
