  • 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!

Be the first to review part HA-4509XD
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!

My Honda Odyssey runs much peppier with the new K & N filter. I plan to stay with your products in the future.

Very happy with how this adaption to my 2005 Honda Civic increases power with no noise. Easy to install, took me two hours because it's more difficult to dissemble the original part in my car in order to install this one. Just what the doctor recommend for me.
