BBR Motorsports has developed a completely new intake/air filter concept for the KLX 110. The U-Flow Air Filter Kit boosts horsepower and throttle response by creating an air chamber between the filter and the carburetor. The U-Flow system turns the filter around so it faces backwards - keeping it shielded from dirt and mud. This innovative upgrade will boost horsepower and deliver a sharper throttle response. It also improves the volume of clean air going into the carburetor - extending the life of your motor.
