Precision Crafted. This Stack Racing Throttle Body is made from a permanent mold casting of 356 aluminum to produce a higher quality casting than conventional sand molds, which reduces porosity for an improved finish.
Application. The Stack Racing 75mm Throttle Body is a direct bolt-in replacement for all 1986 to 1993 5.0 Mustangs. 75mm throttle bodies work great on heavily modified or supercharged 5.0 mustangs, this is because stock or mildly modified 5.0's do not flow air enough to benefit from the larger Throttle Body.
Technical Note. The 1986 to 1993 5.0 Mustangs must run both a throttle body and EGR Plate with all stock connections functional to maintain street legal.
