      Product Information

      Features, Description, Reviews, Q&A, Specs & Installation


      • Perfect for Force Inducted or Heavily Modified GT's
      • 90mm Single Bore Design Improves Airflow
      • CNC Machined from Billet Aluminum
      • Bright Polished Finish with Ford Racing Logo
      • Dyno Tune Required
      • Fits 2011-2014 5.0L GT Mustangs


      More Air, More Power. Replace your Coyote Mustang's restrictive factory throttle body with a Ford Racing unit that allows your heavily modified engine to breathe easier with its free flowing 90mm single bore design for excellent performance gains.

      Ford Racing Quality. Precision CNC Machined from solid billet aluminum to ensure the highest quality, this Ford Racing 90mm throttle body comes fully assembled, complete with throttle position sensor, actuator motor and even includes the jumper harness. Featuring the Ford Racing logo CNC machined into the housing, this is the only Coyote throttle body backed by Ford Racing.

      Required Upgrade. To realize the full power potential that this Ford Racing Throttle Body has to offer, AmericanMuscle highly recommends the use of a Mustang Handheld Tuner to reprogram the vehicles computer (ECU) for proper operation.

      Required For Installation:
      • Ford Racing Adapter part# M-9474-M50 is required for installation on the stock OEM Coyote intake manifold.
      • Ford Racing Adapter part# M-9474-M50B is required for installation on the Boss intake manifold part# M-9424-M50BR.
      Application. This Ford Racing 90mm Throttle Body is specifically designed for use on a heavily modified 2011 to 2014 GT Mustangs equipped with the 4-valve 5.0L V8 Coyote engine.

      Technical Note. 90mm bore throttle bodies work great on heavily modified or force inducted GT mustangs. Stock or mildly modified GT's do not flow air enough to benefit from this larger Throttle Body.

        Great throttle body.

        This throttle body is great. But if you plan on putting it on the Holley sniper efi intake manifold you will need a throttle body spacer as the TB motor housing hits the intake manifold before it meets the gasket landing.

        Ford 90mm throttle body

        Great throttle body! I installed this on a 2014 GT automatic. Fit and finish is incredible. I can’t really comment on The power difference from just the throttle body since I installed it with a programmer and intake as well. But with the air raid racer intake, Bama tuner, and ford racing throttle body, WOW!!!! The difference is incredible

        If you have the little extra money and want only Ford Performance “quality” parts then the feel, finish, whistle, and slight performance edge this beautiful piece will give you will not only make you crack a grin every time you pop the hood but it will constantly remind you that you made the right decision. Enjoy!

        90mm Ford Performance throttle body

        The throttle body looks great and does make a difference in the performance of my Boss. It is a little tricky to get that TB tuned just right to make a difference in the performance. Originally had BAMA send me three different tunes which did not work at all. They were great out of the whole, but once I hit 5000 rpm's the motor fell flat on its face. I ended up taking it in to get a professional tune done and it made the world of difference.

        This thing is sweeeet. Definitely get pumped to pull this out the box! Not only does it look like a gem under the hood but paired with the Boss 302 I.M. I got some major power gains! However they do not make a coupler to fit this so I did have to order and custom cut my own to fit my Airaid CAI which I wasn't prepared for. Not sure how it will be for others tho. All in all, extremely happy with this product.

        4 2014 GT - JordanS Installation Time: Shop Install Installation Cost: $100-$250

        Great final bolt on upgrade

        First off, I'm an amateur under the hood. I've put on a CAI and that's about it. I got through most of the install on this without a hitch until I got to the wiring harness. The install instructions made it seem a little easier then it was and I ended up destroying one of the wires trying to get it out of the factory harness. So I had it towed to my mechanic and they replaced the wire and installed the TB for me. After bouncing back a data log with Bama tuning they fixed a very bad cold start issue I had going after the install. After the 2nd tune upload my car is running like a CHAMP! I don't notice very much performance change because I have full exhaust, CAI and a tune. The biggest difference I noticed was the fact it fixed many of the issues my car was having. I was having an issue when I first got the car with my RPMs dropping too low and the engine stalling randomly while coasting in nuetral. The only way I could fix it was to up my idle rpm to where it didn't go below 900. After installing this throttle body I no longer have to boost my idle RPM through the tuner to keep it from stalling. It goes all the way down to 650 (where it's supposed to) and doesn't drop below it at all. I also am able to let my car coast in gear without giving throttle and it maintains speed. Before it would make a chugging noise and start to lose speed faster than it should've. I am thrilled with the purchase and finally have my car driving the way it should've all along. I am giving 4 stars because it's stupid that you have to rewire the harness for it to work. Other than that it's a solid purchase that looks and drives the part. Also it's nice because most people have the BBK 90mm so you stand out more with this one. Sorry for the long review.

        Throttle body looks like a gem under the hood

        The 90mm throttle body was a great upgrade. Not only does it look great, I could feel and hear the difference. I'll know more once the weather improves and I drive a bit more and analyze the performance changes. Two tips: It was difficult to re-wire the one stock connector as far as removing in the pins to insert into the new connector. I used the safety pin, but placed it on the left side when looking down and pried inward of the pin opening as I pulled on the wire. Also, when using the stock air tube follow the submitted instructions for sawing about 1.5", just after the rubber hose clamp portion. It was difficult to find a silicone coupler and I recommend AM offer a part for this upgrade. I found Precision Turbo out of Hebron IN offered a 3.5" to 4" multi-layer coupler that worked perfect and looks great. Probably would have taken under an hour if I hadn't dropped and lost a screw and had better advice for the rewire.

        Beautiful Quality Piece, Nice Gains

        First, I'd like to say that this is a beautiful throttle body. If you showcase your Coyote, this is the throttle body you want sparkling at the judges. As far as performance, I did see noticeable gains. I saw huge gains once I installed headers and an x-pipe. Right away, you'll hear the throttle body taking in way more air than stock. I used this in conjunction with the BOSS 302 Intake and there is a little bit of modification needed to the wiring. No worries, the instructions from AM customers were spot on. Great product!

      DYNO Tune? will a BAMA tune work or does it have to be dyno tuned? Also i have a AirRaid CAI and a BOSS 302 intake will that work with this?

      • YES, your throttle body will do great with just a BAMA tune....your cold air and intake will love your new throttle body......remember to do something to get all that air "out" the back

      Will this FP 90mm TB fit the Sniper intake manifold with 90mm opening and fuel rail kit? If so, will it require any additional adapter kits?

      • The Ford Performance 90mm Throttle Body will fit the Sniper Intake Manifold without the use of an adapter.

      Is it a bad thing to install this on a lightly modified GT? if so what TB should i go with?

      • The 90mm throttle body can be used on lightly modified GT's, however, it is designed for forced induction vehicles as well as high RPM naturally aspirated built engines. The throttle body that would be recommended for a lightly modified 11-14 GT mustang would be the 85mm throttle body item 56145.
