More Power. Increase the airflow in to your Supercharged or Turbocharged 5.0 Mustangs engine for an improvement in throttle response and more horsepower you can feel with a SR Performance 75mm Throttle Body. Precision Crafted. This SR Performance 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 SR Performance 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. Reuses the factory Throttle Position Sensor (TPS).
