K&N X-Stream Air Flow Filter Assemblies, Tops and Elements

K&N unlocks the power with the new X-Stream Air Flow Top.
Not only does the K&N X-Stream add filter area, it actually redirects airflow inside the filter to pull in more air through the side pleats for even greater performance efficiency. Cleanable and reusable, the X-Stream Air Flow filter delivers the best protection available for your engine, and comes in a wide range of sizes and colors.

Features:
  • Most surface area possible for restricted clearances
  • Sizes include 9", 11" and 14" diameters
  • Color rings include black, red, blue, and polished
