Uni Filter Dual-Stage Foam Air Filter

• Traps dirt and dust in 2 layers of foam
• The large pore, pre-filter captures the bigger particles
• The small pore, inner filter prevents any engine-wrecking grit from reaching the cylinder
• Used by Kawasaki, Yamaha and Suzuki offroad teams 

For over 50 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.

Uni Filter entered the air filtration industry in 1969 with a simple concept "Let's design an air filter that works." And that's exactly what we did. We chose polyurethane foam as our air filtration medium, instead of paper or gauze, because of its superior dirt-capturing capabilities and its capacity to be easily cleaned and reused. And the rest is history. Uni Filter products perform their best in the worst of conditions. That's why Uni has been the chosen air filter of all serious offroaders for decades. In this dirty, dusty environment, air filtration is extremely critical to the performance and protection of the engine. The Uni Air Filter's ability to hold extreme amounts of dirt and still provide excellent airflow and performance has made Uni Filter the choice of some of the greatest racers of all time.
