    • Polished Finish
    • Fits 1996-2004 4.6L GT Mustangs

    Review & Installation Video

    Dave from AmericanMuscle, today I have the stack racing 70mm throttle body, designed to fit the 96-2004 Mustang GTs. This will exclude the Cobra and Bullitt as they have a different style throttle body. The idea of a throttle body is to continue to give y

    More Power. Increase the airflow in to your 4.6L engine for improved throttle response and more horsepower 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 Polished Throttle Body is designed to be a direct fit replacement on the 1996 to 2004 4.6L SOHC GT Mustang. 70mm throttle bodies work great on stock or mildly modified GT mustangs.

        Does this require a tune?

        • Just adding a larger TB to your car will do little in performance, but enough that you should notice the change. Adding any performance item, a tune will give you the most it is capable, but it's not needed to feel it. Most times, just disconnecting your battery for five minutes will let the computer drop it's programming of how the car was driven before. Once you reconnect the battery and drive it a few days, it will relearn the new stuff added. You will notice the gain once the computer relearns. Things like cold air intakes, etc will just add to that. You just want to be sure nothing is blocking all that air getting into the engine.

        What can I expect with this mod alone. I am debating on whether to buy this or not. How much HP and ft/lbs would I expect but just using this mod alone. My engine is bone stock so when this mod alone ( no tune , CAI , or intake plenum ) what gains will I see performane wise ?

        • Better throttle response, and <10 hp at wide open throttle. If you were to get a tune for it you would see more gains from it for sure. If you planned on doing more mods the SCT tuner would really be beneficial. I would do all your modding and then get the tune to include all the mods. So buying the CAI - SCT Tuner package last would be my suggestion. You can tell Bama tuning all the mods you have done and they will write you a tune that will get the most out of all of them. It's not cheap to mod a Mustang, just take it one step at a time, and have fun!

        Hello, Is this throttle body legal in California?

        • Unfortunately the SR Performance 70mm Throttle Body is not certified and approved by the California Air Resource Board meaning this Throttle Body will be illegal for use upon highway/road in California.

        I already have a cai. I was wondering if I needed to buy a tuner along with this throttle body.

        • Hello! A tuner is not required for a throttle body installation, however it will definitely add more power and make the throttle body run a little more efficiently.

        Hi, I have a 96 GT and was wondering what the difference is between this product, the 70MM SR throttle body, and the SR 75 MM. Now obviously the latter offers better airflow to the engine, but is it a good idea to choose the 75 MM over the 70MM if I do have an updated plenum? I installed a SR cold air intake a couple of weeks and was just wondering which throttle body would be best for my GT. Thank you 2 answers
        will this be fine with no tune? I'm thinking about getting this with the sr performance plenum. But I do not have a tuner. My gt has a full exhaust, cai , coils, fuel injectors. Will the motor still run fine with more air going in even without the tune? 3 answers

            Nice looking and awesome

            Very happy with this purchase. Also bought the plenum to go with it since the price was great! One issue. When connecting the stock throttle cable it would not fit in the hole. I carefully drilled it to make it fit, other than that very happy with it!

            SR 70mm Throttle Body

            Good quality item and best bang for your buck. I added this to my SN95 GT with a SR Performance CAI and a BAMA tune. Would highly recommend if your going to stick with a NA 4.6, but are also looking for some increased power and throttle response.

            Very poor quality product

            To start I absolutely love American Muscle and everything you guys do, but....as for SR performance for this throttle body is honestly the worst product that I have ever purchased for my mustang. It has poor construction, metal finish looks nothing like the picture it’s supposed to be polished aluminum but it’s actually flat, throttle body cable doesn’t fit in the hole and you have to dermal it to get it to fit. And that’s not even the worst part. The Worst part is the Throttle body position sensor assembly, it is supposed to be OEM and fit flush but ends up having a gap in between so it doesn’t work properly won’t allow your car to shift through the gears properly and give you a check engine light. Even after buying a ford motocraft TPS it ended up not working at all so I was out an extra $150 buying aftermarket then the motocraft sensor, so that was very disappointing. So for all you Automatic newedge owners out their don’t be fooled by the low price it’s a cheap product and I would not recommend buying this throttle body for your mustang! Spend the extra $100 and buy the BBK throttle body instead. I hope this helps you guys not make the same mistake as I did and avoid all the problems this product has given me. AM you are the best! but SR performance really dropped the ball on this one.

            70mm Throttle Body

            Took about 10 mins to install, came with new gasket and new hardware. The only problem I had was that the hole that the throttle cable slides into still had a bit of metal frm drilling still attached, no big deal, just got a drill bit and cleaned it out.

            Bolt-on w/ some modification

            throttle body is a relatively easy install. Would have been really easy if the hole for the throttle cable was drilled out right. We had to bore the hole out more so that we could install the cable. Would have been helpful to know this ahead of time and should be outlined in the instructions that you may need to drill.

            Good value

            Worked well. Picked up a few horsepower, and much better throttle response. Whistles a bit under partial throttle, but nothing too bad.

            Noticable Difference

            The throttle body came well packaged and all hardware and gasket was included. Easy installation althou had to drill the hole for the throttle cable, just a little bit you could probably do it with sandpaper that is how much you need to do. It woke the engine up. It looks great with the polished finish,and has better starting, throttle response, even shifts better and sounds awesome!! You can definitely tell difference when you get down on the pedal! Highly recommend! Thanks again American Muscle
