I have a used Uni Filter 2 Stage filter for a KTM.
From the manufacturer:
"For over forty years, Uni Filter Dirt Bike Foam Air Filters have been unsurpassed in both engine protection and overall performance. And their unique two stage design produces MORE HORSEPOWER and MORE TORQUE than any other air filter."
- Unsurpassed in airflow, stopping dirt and overall performance
- Two-stage air filters come apart for maximum airflow and ultimate cleaning
- Most filters feature the Ultra Seal grease groove on the sealing surface
- Clean easily with grease-cutting dishwashing detergent; just clean, oil and reuse indefinitely
- Made in the U.S.A.
