The K&N RU-3112HBK is a high-performance universal clamp-on air filter engineered for custom intakes and specialty applications where high airflow and easy maintenance are required. This filter features K&N Dryflow media, a specialized oil-free synthetic material that provides excellent filtration efficiency without the need for traditional oiling. The black synthetic media offers a clean, stealthy aesthetic for modern engine bays while maintaining the rugged durability K&N is known for.

Built for versatility, this tapered conical filter uses a 4-inch flange for secure attachment to intake piping. Because the Dryflow media is non-oiled, maintenance is simplified; when the filter becomes dirty, it can be quickly washed using K&N synthetic air filter cleaner and reinstalled once dry. This design ensures consistent performance and a long service life across various automotive, industrial, or racing setups.
