Air Filter Kit - U-Flow / KLX/DRZ110 02-Present BBR's exclusive U-Flow Air Filter System turns the filter around so it faces backwards, keeping it shielded from dirt and mud. It comes with a high-volume oversized Uni filter maximizing air flow. This innovative upgrade allows the bike to be jetted for optimum performance. The U-Flow delivers a high volume of air to your carburetor resulting in sharper throttle response. Complete kit includes adapters to fit stock KLX/DRZ110 carbs along with the Mikuni VM26 and Keihin PWK/PE28.
