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!

K&N HA-4517XD Air Filter Product Reviews

Monday, February 11, 2019 - Part HA-4517XD
I am happy that K&N finally made a filter, only took 3 years. I am disappointed that the total area of the filter is so small. It is a lot smaller than a foam filter. I assume it is so short so it can accomodate to the bikes that have batteries. (Mine does not) however I’m glad to have a K&N.
