      Review & Installation Video

      Hey I’m Justin with, here with a great bolt on for any modified 2 valve, I’m talking about the SR Performance 75mm throttle body, fitting all 96-04 Mustang GTs. SR Performance has really made quite the impact on the aftermarket Mustang world thanks to their variety of performance and suspension components, with prices that do fit nicely into just about anyone’s budget. To see more of what SR has for your ride in addition to new and exciting products, you have to subscribe to our YouTube channel by clicking on the banner below, if you haven’t done so already. The 75mm option from SR Performance is in my opinion a great bolt on for anybody with a heavily modified or boosted 2 valve and really does compliment an aftermarket throttle intake, and intake spacer. On the other hand if you do have a stock or lightly modified 2 valve then I would recommend going with the SR Performance 70mm option instead, otherwise you might end up hurting performance rather than helping it. That’s just because a lightly modded or stock motor really isn’t moving enough air to justify the larger opening with the 75mm option. Either way, if you’re not quite sure which option to go with, you can always get in touch with one of our Mustang experts, they’d be happy to talk about your setup and make a recommendation based on your mods. Taking a closer look at the throttle body itself you’ll see it is made from a 356 grade cast aluminum, which gives it this smooth, almost polished type of finish. The throttle body does not require a tune but we do recommend running one just to get the most performance out of each mod. Especially if you do plan on pairing this up with an aftermarket upper intake plenum, and spacer like I talked about a little earlier. SR Performance does offer their version of both of those which you can find on the product page of by clicking on the link below. Included in the box you’ll find all the necessary hardware and gaskets needed to get the job done. The actual install itself is pretty straightforward and should only take you about an hour using some basic hand tools. You will need to transfer over the throttle position sensor from your old throttle body, to the new SR Performance throttle body but it’s only two screws and pretty straightforward. In addition to attaching the throttle cable to the throttle body. So if you’re looking for a solid upgrade to your heavily modified 2 valve or 6 then be sure to check out the SR Performance 75mm throttle body, available right here at

      • More Horsepower
      • Better Throttle Response
      • Great for Supercharged GT's
      • Polished Finish
      • Fits 1996-2004 4.6L GT Mustangs


      More Power. Improve the throttle response and horsepower of your worked or Supercharged 4.6L engine 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 Polished Throttle Body is designed to be a direct fit replacement on the 1996 to 2004 4.6L SOHC GT Mustang. 75mm throttle bodies work great on heavily modified or supercharged GT mustangs, because stock or mildly modified GT's do not flow air enough to benefit from the larger Throttle Body.

        5 1998 GT - CaptainAwesome Installation Time: Afternoon

        Feels Good

        Feels good when you press the gas pedal now. The stock throttle body didn't do anything until it was at least halfway down. Like everyone else I had to slightly widen the cable hole, using a dremel. I got the stock rubber air to fit by running it under hot water for a minute, it stretched over so easily. Those little sensor screws that Ford locktited in were a pain though. I cut the first one out, then bought a "1/2 in. Manual Impact Driver Set" to hammer the second one free in four good hits.

        Good product

        The install was easy, I did have to make the throttle cable hole bigger, I purchased the plenum too. I definitely feel more throttle response and car pulls harder after 2500 rpm.

        Throttle Body Intake

        I think this is a solid product that is well built. Had only one slight modification to make with the throttle cable hole insert that had to be slightly drilled out to fit the old cable (17/64"). Worked great and no error codes have appeared. Looks like a great modification.

        Install was pretty simple. Everything fit great. Now i can really hear the car sucking air in to feed the beast. Just a small bolt on but worth every penny.

      I have a 97 4.6 gt. Will I gain more hp and torque by installing a larger tb to and plenum?

      • With a good tune, yes, but numerically you're not getting really getting more than 10+. The idea is once you install a larger throttle body and plenum, you will be opening up the airflow of your Mustang, allowing it to breath better so other performance modifications can get you that extra hp/tq you're looking for.

      Will this make a noticeable difference on a 04 GT with just a CAI? I have an 04 mustang GT with mostly cosmetic upgrades besides a CAI. I was wondering if a throttle body will make a difference on my stang even though the engine is pretty much stock besides the CAI. Will this hookup to an aftermarket SR performance CAI? Finally, if it would make a difference, what mm throttle body would be ideal for my vehicle? Thank you!

      • I would get the plenum and throttle body together. The upgraded throttle body with stock plenum will have some restriction. I have a cold air intake, upgraded plenum and 75mm throttle body. Its a decent upgrade ,some people believe brands make a difference, which I dont agree with. Dyno test results prove that its only one horsepower or so. I have the sr throttle body ,which installed very easily. 70mm or 75mm is fine.

      Will this TB work with the stock plenum? I realize there would be some air restriction issues, but I still want to keep my stock plenum for cosmetic reasons.

      • Hi,This SR Performance 75mm Throttle Body is too large for your build I suggest the SR Performance 70mm Throttle Body Item #41103 it is designed more for the stock or mildly modified GT Mustangs.

      After installing the intake, throttle body and plenum, would a tune be good enough for the extra gains or are there other mods I need?

      • The SR Performance 75mm Throttle Body is a very large throttle body and would work very well on supercharged applications, as well as highly modified naturally aspirated engines with mods such as longtube headers, cams, etc. Typically we recommend a 70mm option for lightly modified vehicles so as to maintain good throttle response.

      Hello all, so i plan on modding my 95' v6 a little before i sell it for a 13' gt in December. But my throttle body broke.. i don't want to put too much money into the car as I'm selling it but i need a new throttle body of course and the 56mm is $250. 60, 65, and 77mm throttle bodies are cheaper but doesn't say itd fit. from looks its the same as a 56 but one of the AM experts told me its fine to do and put onto my v6, any ideas before i pay for it? please help!! 1 answer
      So, I have read a few different responses. With a stock motor, SR performance CAI and flowmaster mufflers (stock exhaust) is the 75mm too big? Some say it causes bogging at low RPM's, other say it runs fine. No plans on going FI or anything, so which is better for a daily driver? 70 or 75mm (coupled with the SR performance plenum). And how will a tune affect anything (planning on a tuner in the near future)? 1 answer
