  • Large surface area for long service life
  • Low restriction

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!

I've have never been disappointed by the quality and value of a K&N filter. I've purchased one for every vehicle I've purchased in the last 25 years. I keep my cars to 200k+, Motorcycles to 80k+, and all sold running well. K&N air filters lowers cost of maintenance, boost performance and efficiency of the vehicle. Acura Legend 290K Toyota Celica 287k, Honda GL1100 91K, Passat TDI 240K, Honda ST1100 89K and Currently Yamaha FJR1300 43K & Toyota Corolla 88K.

No issues out of the box; filter fit right in place within the factory Honda box. I can tell an improvement in power when I step on the gas, which is needed out of a 4 cyl engine. Have used K&N Filters in my V8 truck with the same increased response. Great product, no complaints
