ProX velocity stack 38.VS3001 Suzuki RMZ 250 2010-2014

The ProX Velocity Stack is an alloy tube that needs to be installed in the throttle body of the Fuel Injection system. The light weight alloy tube is specially designed and developed to adjust flow so that the engine gets improved bottom power at part openings, plus better and smoother throttle response without re-mapping the ECU.
The ProX Velocity Stack will significantly improve drivability and increases torque at the lower rev range, exactly the area where the power is needed!
