The Twin Air Replacement Air Filter for PowerFlow Kit is designed to provide dependable filtration and efficient airflow for select youth off-road motorcycles. Manufactured by Twin Air, this replacement filter uses a thick, flat foam sealing ring to maintain maximum contact with the airbox while functioning as a breathable gasket. Its greaseless design helps support consistent air passage and reliable engine intake performance.
The filter features a coarse open-pore foam outer layer that captures airborne dirt, grime, and sand before they reach the engine. A fine open-pore inner foam layer provides a second stage of filtration for smaller particles while maintaining strong airflow. Twin Air’s exclusively formulated adhesive is designed to withstand repeated cleaning, including cleaning with harsh solvents or gasoline, helping extend the service life of the filter when properly maintained. The filter is slightly smaller than the stock design to increase air space and circulation around the filter.
