K&N Universal Clamp-On Air Filter 3in Flange ID x 6in Height

Upgrade engine airflow with the K&N Universal Clamp-On Air Filter. Features a 3in flange, 5in base, 3.5in top, and 6in height for maximum airflow.

The K&N Universal Clamp-On Air Filter (Part # RU-1039) boosts engine horsepower and acceleration with maximum airflow.

Built with a round tapered design, this universal air filter features a 3-inch flange inside diameter, a 5-inch base outside diameter, a 3.5-inch top outside diameter, and a 6-inch overall height. Constructed from multiple layers of oiled cotton gauze media housed between aluminum wire mesh, it captures harmful contaminants while maintaining high air velocity.

The ultra-strong, pliable rubber flange absorbs engine vibration for a secure clamp-on fit. The rubber material can also stretch up to 1/16th of an inch (1.5mm) to accommodate slightly varied intake pipe dimensions. The filter is fully washable and reusable, offering a durable, long-lasting performance solution.
