Universal Clamp-On Air Filter

The K&N RE-0850 is a universal clamp-on air filter engineered to enhance performance and protection across a diverse range of applications, from racing vehicles to tractors. Its design accommodates various intake angles and offset diameters, making it a versatile filtration solution. The filter utilizes ultra-strong molded pliable rubber flanges, which not only provide a secure attachment but also absorb vibrations. These flanges can be stretched slightly, up to 1.5mm, to ensure a snug fit on various intake systems. Constructed with K&N's signature oiled cotton media, this filter is washable and reusable, offering a long-lasting and cost-effective alternative to disposable filters. K&N has been a leader in filtration technology for over 50 years, with this high-flow air filter originating from designs developed for demanding off-road environments. Its state-of-the-art filter media is intended to increase horsepower and acceleration while improving overall engine performance. Key specifications for the RE-0850 include a 4-inch flange diameter, a 6-inch base outer diameter, a 4-5/8 inch top outer diameter, and a height of 6 inches. The washable and reusable nature of the filter aligns with K&N's commitment to providing products that increase performance, protection, and longevity.
