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.

Q & A (3 Questions, 6 Answers) Ask a Question

Would this run well on my almost stock 2003 mustang gt? I have an almost stock 2003 mustang gt, I've got an offroad h-pipe and an AEM Brute Force Cold Air Intake. I just installed a short throw shifter as well. I'm in the process of modifying my mustang a little bit over time. Eventually I will get a supercharger, but that probably won't be for another year. Would this throttle body be too much for my car even If I purchase the throttle body spacer, sr performance intake plenum and intake spacer at the same time? Would it cause any problems? How much gain would I see in horsepower with this product?

  • With the mods listed, I would suggest a 70mm. But since you plan on supercharging, I would definitely use the 75mm or maybe even a 78mm. The problem with being near stock and having a 75mm, 78mm, or bigger, is that your engine cannot produce the power that the throttle body is demanding, causing a sensation of being "bogged" down. So, if you have a few basic bolt-ons anything bigger than a 70mm is just an overkill. Hope this helps!

75mm really to big unless supercharged??? I keep seeing that everyone is saying that at 75mm or 78mm is too large for a naturally asperated engine. With that being said, why is it that they AM installed the BBK 78mm on their factory GT with a CAI and Exhaust (as seen in th GT power mods video). I have a JLT CAI, underdrive pulleys, long tube headers, offroad h-pipe, and flowmaster exhaust. All of this with a custom tune. Is a 75mm still too large of an TB?? just seing a lil bit of contradiction here.

  • Absolutely not, I used a 75 mm throttle body, intake elbow, cold air intake (from the fender) and an x pipe with pulleys and it transformed my 99 GT.

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.

    Great throttle response. Much better than stock. Very easy to install only took me about 20 minutes. Only one small problem with the install and I already knew about it. The mounting hole from the throttle cable is too small. You need to fine tune it with a round file or a slightly larger drill bit. Otherwise you'll have to tap it into place. Try to test fit it before you actually mount it.

    This is a nice throttle body. I suggest having a vise and drill handy. You'll have to drill the holes out for the throttle before the install. Other than the time that takes, the rest of the install takes about half an hour. Good throttle response.

    Pure Power!

    May 11, 2012

    I Debated on this one (75mm) or the 70mm. Go big or go home right? Got the 75mm and I'm not regretting it one bit! It was so easy to bolt on to my SR Upper Plenum (also have the spacer). Of course I had to drill the throttle cable hole a little bigger but it was easy. I Reprogrammed the car after installing the TB and dang could I tell the diffrence! Would recommend to anybody! The TB goes great with StackRacing plenum and spacer! Thanks AM and SR!! :)

    This is a great product is polished inside and out. Matched it to a Trickflow 75mm plenum and the throttle response is bang on. Easy to install. Comes with gasket, bolts to bolt onto plenum, and screws to hold the throttle position sensor on.

    Decent throttle body for the price. Although the hole for the throttle cable was too small. And it seems to "stick" closed sometimes..
