  • Large surface area for long service life
  • Low restriction
  • Washable and reusable
  • Outstanding filtration
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!

Very efficient filter. Good instructions both online and enclosed with the packaging. Simple straight forward replacement for my old filter. My car is a 2013 Honda Fit Sport and the exchange took less than 5 minutes to accomplish. I also have a cool air kit with the K&N ait filter and it works great! Thanks - Keep up the good work.

I have a 2014 Honda Accord LX, and was kinda interested in purchasing an intake system for it. Looked it up at KNFilters.com and found it was a great product. Ordered it right away. The Intake was installed and is the greatest invention ever made! Delivered Friday, installed Saturday. Thanks for the quick shipping on that.
