Butterfly face plate is made from a solid chunk of billet alum. that is CNC precision machined so butterflies will seal properly making setting the idle a snap. Simple to install with ten bolts and a bead of silicone between the faceplate and injector housing.
Faceplate is drilled and tapped 1/4-20" for barrel valve and throttle cable bracket mounting. Throttle stop pads are machined into the sides of the faceplate.
Butterfly bore size is 5.00" and included are three red 5.00" butterflies. Face plate weights six and half pounds as seen in the pictures and will fit all Enderle Big or Short and Ugly injectors but the Little Ugly injector uses a different butterfly faceplate.
