Description

Stock air filters restrict flow and require frequent replacement—the UNI FILTER NU-4136ST delivers superior airflow while remaining cleanable and reusable for the life of your bike. Two-stage construction separates for thorough cleaning with standard dishwashing detergent, then oils and reinstalls in seconds. Built to fit your Honda CRF250 or CRF450 exactly like OEM, this U.S.-made filter outperforms disposable alternatives in both dirt-stopping capability and performance consistency.

Helps keep cool, works great!
