The SFG throttle body is the basis of the bodies that have proved so successful in the World, European and British Touring Car championships. It is normally configured to supply one or more banks of cylinders via a manifold and is suitable for use with high levels of boost. The lever mechanism has two springs and gives a rising-velocity opening rate. ‘O’ rings, throttle pot clamp and fitting kits are supplied with all sets. Ideal as a performance replacement for many engines using an original single throttle body. This assembly is supplied complete with throttle linkage attached. Height is 80mm.
