The Mines High Flow Throttle System firstly widens the diameter by 2.5 mm to increase the absolute quantity of air flow and secondly achieves the ultimate air flow efficiency by eliminating the unevenness of the internal surface and by modifying the butterfly shaft and bolts. The internal surface is machined with a ultra precision diamond tool and then is mirror finished to transform the surface to an ideal “ventur tube” shape. The product promises the ultimate throttle response experience. Mines highly recommends a modification of ECU in order to enjoy the maximum potential of the Highflow Throttle Body.
