K&N XStream Series Motocross Air Filters take performance to the next level with the addition of a filter within the filter's top in order to add even more filtration area for high air-flow and capacity. Each filter piece has pleated media which creates a large surface area that provides high airflow and great dirt holding capacity for extreme conditions. The two-piece design eases installation and removal on modern narrow-framed MX bikes. The epoxy-coated aluminum wire mesh, incorporated into a backfire screen, protects the filter element from harmful debris. A custom base seal ensures a precise and secure fit. K&N air filters are washable and re-usable and they come pre-oiled and ready to use!

Loved the air filter. Made the bike sound good and helped with the throttle response. Sadly my bike no longer runs.

Easy to install, Noticble power increase and better sound. K&N is clearly the leader in the air filter bussines. I dont know why most dirt bike riders still use the old foam filters!
