The ProX Velocity Stack will significantly improve drivability and increases torque at the lower rev range, exactly the area where the power is needed! 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 whithout re-mapping the ECU.

Note: This is an exemplary illustration. Versions differ depending on the model. Delivery includes one velocity stack only.
