Product Description

The K&N RC-1250 is a high-flow universal clamp-on tapered air filter built for a wide range of performance and utility applications. Its cone-shaped design maximizes filter surface area within a compact 4-inch tall package, delivering excellent airflow and filtration efficiency across racing vehicles, motorcycles, ATVs, generators, and more. The multi-layer oiled cotton gauze construction flows significantly more air than any paper element, translating to improved throttle response and horsepower gains on virtually any application it's fitted to.

The centered 2.25 in. rubber flange mounts securely onto matching intake tubes, absorbs vibration, and can be stretched slightly to accommodate in-between sizes. A chrome metal top cap gives a clean, finished look under any hood or airbox. Washable and reusable, the RC-1250 arrives pre-oiled and ready to install, and is backed by K&N's 10-Year/Million Mile Limited Warranty. Made in the USA, it's a proven long-term upgrade for any build requiring a compact clamp-on tapered filter.
