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 UNI UP-4152ST filter has the following dimensions
- 3.5" (89mm) overall OD
- 1.5" (38mm) inlet ID
- 4" (101.6mm) installed height
- 0° straight inlet, no angle
Both stages of the filter should be pre-oiled before use, use only foam filter oil made specifically for foam style air filters.
