Description
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 stock 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.

Will this work with my cold air intake This might be a dumb question but will my cold air intake fit this TB or do I need to buy a 70mm tube for my air intake as well?

Gtowner Year: 1993 Model: GT

  • As with most after market throttle bodies, it should have a bevel where the spot for the tube is stock size and the blade is larger then stock. So yes it should work for your c.a.I.

I have a 1987 LX 5.0 with the Speed Density setup. Will this work with it? I have a 1987 LX 5.0 with the Speed Density setup. Will this work with it? I know many parts will fit correctly, but compatibility with SD is different. I just ordered a new CAM after about 2 weeks of research. I know it would be far easier to get parts i f I switched to MAF, but i (quite frankly) do not want to.

dbente Year: 1993 Model: Other

  • I don't know much about speed density, but I would think that it would. It's basically just a throttle body. Yours has egr, Iab valve and tp sensor on it, doesn't it?

I have a 1992 5.0 gt, I want to get this and a cold air intake, would I need the erg plate or spacer? It's a completely stock car, I just want more of a touchy throttle. Thanks

    Stack Racing 70mm Throttle Body

    I purchased this 70mm throttle body for my 1989 Mustang LX Coupe with a built 5.0 in it. The install was fairly easy, I did it by myself. My old throttle body was the dinky stock one, let me tell you putting them side by side is a huge difference in size. Once I put on the new throttle body and EGR Plate it already made my under hood appearance look better with it's great shinny finish from the polished aluminum. I did have to re-use 1 gasket because of the type of aftermarket intake I have (Edelbrock) so it pays off to be careful when going out with the old and in with the new. After it was installed I had to start my car and turn it off a few times to let the computer fix itself and fiddle with the idle screw a bit and then it was good to go. The throttle response after install was much better, it picked up speed faster and made it even easier to break traction at the rear wheels. Hope this review helped. Thanks.

    Great Product at a great price

    Great quality and finish. Why pay more for other brands. Savings allowed me to buy other parts. I did the whole intake, headers and full tune up so I can say specifics on parts performance but works great and looks good.

    Installed on a stock 5.0 that was lacking the throttle response that I like from carberation. This product installed very easily, Follow the instructions to set the TPS and IAC and it works very well. The throttle response is great and what I was looking for. It even changed the sound to a little deeper tone. Only one issue and that is a sqeek in the linkage hope to get that found and eliminated.
