    Review & Installation Video

    Hey guys, Stephanie with, here with a review of the GMS twin 62-millimeter throttle body, 2005 to 2010 GT Mustang. A throttle body by itself isn't really going to net you much in terms of horsepower, but an aftermarket throttle body upgrade like the GMS twin 62-millimeter here does compliment other bolt-ons like cold air intakes, headers, intake manifolds, and cams. It's really gonna work well with forced induction setups. If you don't really have much done to your car at this point, but you're looking to make more power, I'd suggest some other items like a custom tune, a cold air intake, or an exhaust just to name a few things before moving onto the throttle body. In fact, you're gonna need a cold air intake anyways in order to install this throttle body. But, if you've done some work already, or you're looking to go forced induction than this would be helpful for you. I'll go over the install in more detail later on, but I can tell you right now I'm gonna call this a one out of three wrenches on the difficulty meter and about 45 minutes of your time. The GMS throttle body has twin 62-millimeter openings, which is pretty standard across the board for aftermarket throttle bodies for the 4.6 liter. But it is a big improvement over the factory throttle body. The larger diameter is gonna allow more air into the engine as long as you have the supporting mods to get the air to the engine and allow the engine to accept the greater amount of air. The throttle body should improve throttle response as well, and that's something that you should slightly notice after installing. This is made from a cast aluminum, not steel, so it's lightweight. It's also gonna have this natural finish for underhood looks, and it comes complete with a new throttle position sensor, which makes it a bolt on install. One other thing that I wanted to mention here is that this throttle body is compatible with the stock manifold, but it does require an aftermarket cold air intake for proper fit. The stock intake will not fit onto the throttle body, so you need a larger intake tube that the aftermarket cold air intakes offer. With that being said, I also have to mention here that a tune is required with this upgrade. Especially if you plan on getting your money's worth from this throttle body. You need a tune to realize the full potential here, but if you really wanted to, you can just bolt this on without a tune. You just won't really see much power benefit.When it comes to price, you're looking at spending a little bit more for the GMS here, because it does come with that new TPS, looking at spending just south of the $400 mark, which is a touch more expensive than other options other than the Ford performance 62 millimeter. The BBK 62 millimeter is about $30 less, but it doesn't come with a new sensor. As far as the install goes, this is gonna take about 45 minutes to install. I'm gonna call it a one out of three wrenches on the difficulty meter. The throttle body already comes with a new TPS sensor, so you won't need to transfer that over, and this is a direct bolt-on replacement. You need a few basic handtools, and that's all. You'll have to remove the aftermarket intake tube from the factory throttle body and note any hoses or connections you remove here since you'll have to re-install those. Disconnect the TPS sensor and the throttle control sensor. After that, you can pull the factory throttle body. There are four bolts, you put your spacer on the manifold, followed by the throttle body. Then bolt the throttle body down, plug back in your connections, install the intake tube along with all the other connections that you uninstalled when you removed the intake tube. Wrapping things up here with the GMS twin 62-millimeter throttle body, this will fit the 2005 to 2010 GT Mustang. Check it out more online right here on

      Great buy for a 15 min install.

      Went with this over the cheaper GT500 option because this one comes with the bolts, spacer, and a new fitting that fits the bigger TB and in my case a JLT intake. Paired with a good tune, my idle is calmer, response is faster, and I don't feel like I'm bogging down after 5k.

      Granatelli TB CAI SCT X4 = bad news

      Bought the throttle body from American Muscle. Bought the cold air intake direct from Granatelli to mate up to the 62mm intake. Bought the SCT from Autoanything (20 off). 6 codes and the CEL. Banks 1 and 2 were lean. Other codes appear to be associated with the SCT. Called Granatelli, they said use the BBK settings on the SCT. There the same. Called SCT, they flashed a new file onto it. Still did not work. Tell me I need a custom tune. Trying to find a company to do the tune in MN. Needless to say, still not installed. Can’t return it because it’s been installed. Brutal experience by all brands, Granatelli, SCT and American Muscle.

      good little bolt on

      Installation was pretty easy and simple. I feel a slight gain in horsepower after the tune. Was my last step to have a full bolt on car.

      Amazing product.

      I went with this throttle body because I loved the fact that it came with all the parts i needed and a throttle body spacer. I wouldnt have to switch the TPI from the old throttle body like the SR or BBK. It also didnt break the bank like the ford racing throttle body did. and it allowed me to purchase the ford racing intake manifold. WOW, it breaths so much better now. All this paired with BBk long tubes and high flow cats, airaid intake, ford racing 47lb fuel injectors, deatshwerks 340lph fuel pump and bama tune to put it all together nicely. Would recommend this anyone looking to add some gains. I still dont have numbers because Im waiting to install stage 2 exedy clutch and ford racing 3.73 gears. You guys can follow my buil on IG P51CCGT. Let me know you guys read my veview and want to know more about my build.

      Twin 62mm throttle body

      Bought this throttle body as part of an upgrade I was doing and it looks great. I did the m90 upgrade on my supercharger and added this to it. I can definitely feel a difference.

      GMS dual 62mm TB

      Basically what GMS did is take the GT500 throttle body and drilled out the plate to make it a direct fit for the GT. So you can save about $80-$100 doing it yourself or you can buy this and it’s done for you. Works great but it is just a GT500 Throttle body not their own brand. Very easy install!

    So what’s really the difference between this one an the ford racing 62mm one ?

    • They will essentially be the same throttle body, and will provide similar performance gains. While this one is a suitable replacement for the factory throttle body, the Ford Performance is recommended for force inducted or heavily modified GT models.

    I have a 09 mustang GT will this throttle body fit a sniper fabricated intake manifold w/ fuel rail kit?

    • This will not fit with the Sniper intake manifolds as this is an ovular throttle body and the Snider intake manifolds will require a circular throttle body.
