In cooperation with several Yamaha teams and riders Twin Air has developed a new Airbox Kit for the Yamaha YZ250F/ 450F
Kit creates more open space within the airbox to optimize the airflow into the engine
The bigger airbox then allows for a bigger Air Filter on the Twin Air Powerflow Kit
Kit includes a Big Air Filter, black Airbox Lid, aluminum cage and sealing ring, air filter bolt, spacer and mounting hardware
Easy to install following the instruction guide
