UNI filters are high flow 2 stage air filters that provide excellent filtering capacity. The 2 stage design traps particles in a progressive manner which smooths air flow before it enters the carburetor. The metal spring internal support prevents filter collapse under high vacuum conditions. UNI filters are cleanable and re-usable, you'll never need another filter.
The NU-4130ST air filter for the 2000-2008 Honda XR650R's will fit the OEM air box and provides good airflow gains. When combined with a carburetor kit it allows maximum airflow into the carburetor thereby producing maximum horsepower. Both stages of the filter should be pre-oiled before use, use only foam filter oil made specifically for foam style air filters.
