THROTTLE B. - VBT

The SPOON SPORTS intake butterfly valve is an OEM Honda butterfly valve that has been reworked, its diameter has been increased and its finish quality is even more advanced.

Its unique machining process makes the duct's inner surface a true mirror, minimizing air resistance and thus maximizing airflow. Its geometry has also been modified to take advantage of the Venturi effect.

Throttle response is significantly improved at both mid-range and high RPMs. Engine power is increased by 4 to 6 horsepower at mid-range RPMs.

The SPOON SPORTS butterfly valve is complete including sensors.
