FA20(TOYOTA 86/SUBARU BRZ) Big Single Throttle



Increasing the diameter of the throttle and in combination with a tapered entrance helps to increase the amount of air the engine can breathe, giving improved performance.
Dimensions are 67mm up from 65mm for the valve diameter and the tapered entrance starting at a diameter of 72mm all maximum size.
With the throttle controlled via drive by wire, the throttle shaft has not been modified to be thinner ; this is to increase the life of the single throttle body by retaining a more rigid shaft. To compensate for this the throttle diameter was enlarged to the maximum possible size.
