Product Description

The K&N RU-3020 is a high-flow universal clamp-on round straight air filter built for large-displacement performance cold air intakes, racing builds, and high-CFM applications requiring a 5-inch flange with a consistent 6.5-inch diameter throughout its 9-inch height. Its straight cylindrical profile delivers a large, uniform filter surface area along its full length, making it an excellent choice for installations where maximum filtration area and consistent diameter are required. The multi-layer oiled cotton gauze construction flows significantly more air than any paper element, translating to sharper throttle response and substantial horsepower gains.

The centered 5.00 in. rubber flange mounts securely onto matching intake tubes, absorbs vibration, and can be stretched slightly to fit in-between sizes. Washable and reusable, the RU-3020 arrives pre-oiled and only needs cleaning every 75,000 miles under normal highway driving conditions. It is backed by K&N's 10-Year/Million Mile Limited Warranty and made in the USA - making it a reliable, long-term upgrade for any large-format performance or racing application requiring a tall, straight-body round clamp-on filter with a 5-inch inlet.
