Advanced filtration technology for enhanced airflow and performance.
The K&N XStream Series Motocross Air Filter is designed to elevate engine performance through innovative filtration technology. Featuring a unique two-piece design, this air filter incorporates a secondary filter within the top, significantly increasing the filtration area for optimal airflow and dirt retention. The pleated cotton gauze material enhances surface area, allowing for longer service intervals and reduced maintenance frequency.
Constructed with an epoxy-coated aluminum wire mesh, the filter is equipped with a backfire screen that safeguards the filter element from harmful debris. This ensures durability and reliability in extreme conditions. The custom base seal guarantees a precise fit, making installation and removal straightforward, particularly for modern narrow-framed motocross bikes.
K&N air filters are washable and reusable, coming pre-oiled and ready for immediate installation. This feature not only contributes to sustainability but also provides a cost-effective solution for maintaining high performance in motocross applications.
