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!

Customer Feedback


After all the issues I hear online about K&N, I thought I should just try one out for myself and see what's the real truth.  I noticed a difference right after installation. It seemed to really help out in the low mid range I changed it out from my foam filter after riding for about 30min so I really did notice it once installed.

Thank you!

What a big difference and better performing oil filter than Honda's OEM oil filters. For the cost and performance K&N takes out Honda oil filters. You can't even compare this filter to OEM is so much better build and quality plus you know your engine is having the proper lubrication it deserves. K&N another amazing product thanks.
