K&N Off-Road Replacement Air Filter (MPN: YA-8518)

Enhance performance with washable and reusable air filtration technology.

K&N off-road replacement air filters are engineered for optimal performance in challenging environments, particularly for off-road riding. These filters ensure clean carburetion even at high altitudes, allowing for consistent engine performance without the need for jet changes. Designed specifically for off-road applications, including motocross, ATVs, UTVs, and side-by-sides, they provide a significant increase in horsepower and acceleration.

The pleated cotton media utilized in these filters offers a large filtration area, resulting in low restriction and high capacity for extended service intervals. With multiple layers of woven cotton gauze, these filters deliver excellent filtration efficiency while maintaining high airflow. They are designed to fit directly into the OEM air box, featuring an application-specific sealing bead that ensures a precise fit.

K&N filters are washable and reusable, with most units pre-oiled and ready for immediate installation. This feature not only promotes sustainability but also eliminates the need for fuel management modifications to achieve enhanced performance. The durable construction and high-quality materials make these filters a reliable choice for off-road enthusiasts.
