      Product Information

      Features, Description, Reviews, Q&A, Specs & Installation


      • More Horsepower
      • Better Throttle Response
      • 70 MM
      • Fits 1986-1993 5.0L Mustangs


      More Power. Increase the airflow in to your Mustangs 5.0L engine for an improvement in throttle response and more horsepower you can feel with a SR Performance 70mm 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 70mm Throttle Body is a direct bolt-in replacement for all 1986 to 1993 5.0 Mustangs. A 70MM Throttle Body is a great upgrade for a stock or mildly modified 5.0 Mustang. Reuses the factory Throttle Position Sensor (TPS).

      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.

        Throttle Body

        Purchased this back in the early 2016 when I had the foxbody and it fit perfectly. Gave a little more HP and had no issues bolting up. Took no time at all to install either. Loved it.
