    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.

    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 ?

    Matt1125

    • 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?

    MrD59

    • 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.

    Sicness

    • 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.

    Does this require a tune?

    Jordan

    • 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.

    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?

    • I personally would add the tune to obtain the full advantages of the throttle body install.

      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

      good for the money

      easy install, throttle response was better and maybe a slight gain in top end. i installed it at the same time as the sr plenum and spacer. i also have a bbk cai installed.

      SR 70mm Throttle Body

      I'm a little disappointed. I received the TB as well as other parts, the gasket had a tear in it and the metal bit at the end of the throttle cable won't fit into the housing.

      car would not start?

      installed the throttle body and noticed that the stock TPS would not attach correctly? had about 1/8 inch gap between the housing and the TPS with screws installed,this is due to the fact that my stock throttle body has a recessed area and the stock TPS has a collar around it that when screwed down fits flush and nicely.Also throttle cable kind of sloppy.Product looked very nice just would not work without making mods.Re installed my stock throttle body and it fired right up so there is a flaw in that TPS part of it.I am returning it for a BBK 70mm unit.It comes with it's own TPS,so hopefully it works,thanks for letting me vent a bit..............

      Bolts right on.....gotcha

      Yeah, so not super excited after spending 5 hours installing he plenum, TB, and CAI. The instructions were worthless if they were included, the parts weren't all there, a gasket was torn, and there were no "helpful hints". Thank goodness for YouTube and the customer review section. The plenum installed just fine the TPS however would not come off the old plenum. Bought a new one just to discover that it doesn't fit flush, figure that one out, no one told you that, atleast they sent extra screws!

      Throttle Body

      overall I am happy with it. A noticeable improvement in throttle response. I have a SR cai plus offroad H-pipe. It all works well together. The only drawbacks were I had to remove a bushing for the iac and the throttle cable hole for cable had to be enlarged, so if it didn't work I would be out since I modified the throttle body linkage by drilling the hole larger. On the good side everything turned out well.

      Was a quick install and combined with the bigger plenum gave it a little more throaty sound and feels like it has a little more giddyup...

      70mm TB

      Simple enough to install but the instructions didn't say anything about removing the black grommet that was already installed in the throttle body. In my 2001 GT the part is not needed. Not much gain in HP but it has a noticeable deeper growl from the tail pipes. A good bolt on for a reasonably priced item.

      I couldnt get the throttle line to fit. I called american muscle and they said it should have fit. They wanted me to send pics to customer service but i didnt have the patience to do all that. I removed it and let it sit in my garage.
