More Power, Better Response. Produce more power and improve throttle response by replacing the restrictive stock factory throttle body with the same throttle body found on the Shelby GT500 along with a 1/2" adapter plate. Shelby GT500 Throttle Body. This upgrade kit includes the same exact Twin Blade Throttle Body that came as standard equipment on the 2007 to 2010 Shelby GT500 upgrading you from 55mm to 60mm for better airflow and more power.

1/2" Adapter Plate. The included 1/2" billet adapter plate is five-axis CNC-machined to exactly match the center of the GT500's throttle body bores with the exact center of the factory 4.6 3V intake manifold bores for a smooth tapered transition. The adapter plate includes required template to modify the GT500 throttle body and an OEM-style seal for a seamless installation.

Bolt-On Installation. The Shelby GT500 Twin Blade throttle body and 1/2" adapter are designed to install in under two hours with just basic hand tools. The GT500 throttle body will need to be drilled out using the provided template.

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

Application. This Shelby GT500 60mm Twin Blade Throttle Body and 1/2" Adapter kit is designed to fit the 2005 to 2010 4.6L V8 Mustangs, including the GT and Bullitt models.

Technical note: The included Shelby GT500 Twin Blade throttle body will require light modification/drilling to install correctly with the included adapter plate.

I bought this set up from another company because AM didn't have it at the time. It was the best way to go without breaking the bank. The GT500 TB with adapter plate works well with the GT. I felt improved

  • You will most likely have to find a silicone reducer boot since the GT 500 throttle body measures about an inch larger than stock. Simple to find and fit.

Answer This Question

Would this fit with a Ford Racing Intake Manifold and BBK blackout CAI? Would I have to drill into the intake manifold

  • I used it on mine and you will need to get a different coupling boot for the cold air kit due to the larger size of the GT 500 throttle body opening. I think mine was a 4-1/2" to 5" boot . Everything else was exactly the same as the stock throttle body on mine. The stock Gt throttle body is just smaller intake opening.

Will this work with the mods I already have listed below? I have a 2008GT that has the ford racing CAI, and also the Ford Racing shaker hood system. I am curious as to the fit of this Ford Racing GT500 Throttle Body Upgrade Kit (05-10 GT) with the above mentioned items. I only ask as for example when I purchased the ford racing shaker hood system, it was not designed to fit really well with the Ford Racing CAI... it took several mods and extra fees as a result of the fitment conflicts.

  • A friend has the same setup as you have and he had to use a Dremel tool and make some cuts at the front of the Shaker system to accommodate the throttle body because the adapter plate adds about 3/8-7/16's towards the front of the engine. Hope this answers your question.

    Great set up but needs the right CAI

    January 20, 2011

    I bought this set up from another company because AM didn't have it at the time. It was the best way to go without breaking the bank. The GT500 TB with adapter plate works well with the GT. I felt improved throttle response and can feel the horsepower. The problem is the CAI you use and if you have the FRPP Intake Manfold. I have a FRPP CAI with a FRPP intake manifold and the set up is nice. BUT the CAI wont fit the TB unless you have an adapter. The adapter that was provided to me by the other company wasn't that great and the way the CAI is shaped didnt help either. I had to cut a lot of the rubber off the CAI to make the adapter fit because when you have this set up, the manifold, TB adapter, and TB push the elbow of the FRPP CAI too far out to fit. Mine has stayed on so far with the way it was rigged but I have plans to change the tubing or buy a new CAI brand. It definiatly is a great TB and an awsome set up. In my opinion get either the JLT CAI or any other brand like it. P.S i also had to place a breather on my PCV valve tube because I had to cut that part out of the CAI in order for it to fit. I hope this long explination helps. Good Luck. I will post pictures soon.

    Great product More Power, Better Response is right. The GT500 upgrade kit was easy to bolt on after I completed the modifications. It took me about 30 minutes to bolt it on. Make sure you get the template or know someone at a machine shop so you can drill out the holes as required. I didn't receive the template. I called to let them know I did not receive the template. I'm still waiting for it. “The GT500 throttle body will need to be drilled out using the provided template." Also would have been nice to know the stock Mustang GT air intake will need to be modified as well. But the car runs great and for me, the kit was well worth the money! The dealer wanted $425 for the stock TB for my 2005 Munstang GT.

    Good performance gains

    March 09, 2012

    Highly recommend this over the BBK unit, this comes with the TPS and motor so there's no fiddling with voltages or anything. However the installation is not exactly straightforward, the holes on the TB are too far apart to fit the stock intake manifold, so you have to drill them. I didn't receive a template with mine but you don't really need it, just make the existing holes bigger so the mounting bolts fit thru. I also needed a larger rubber intake coupler that I ordered from siliconintakes, would be nice if it was included with the kit. Finally after hooking it up I got a lean engine code so a custom tune was required, even though my CAI is a no-tune. I guess the TB and CAI combined required a tune. Noticeable improvement in performance, some people say a TB doesn't add much top-end HP which might be true, but you definitely feel it when accelerating. It's just like adding a CAI, feels like the car can 'breathe' better. Also increased my intake sound as it's sucking in more air now. Highly recommended!

    Awesome upgrade for the money!

    March 12, 2013

    This throttle body was indeed a breeze to install. I installed it with an Airade CAI and a 91 octane performance tune and WOW!!! Major difference in acceleration and throttle response. I would strongly recommend taking the throttle body to a machine shop to have them mill the new holes using the proper size end mill bit. Since the throttle body already has mounting holes, you cannot simply drill into them and center your new holes without possibly causing damage.

    More air, more power!

    January 20, 2013

    GREAT product! much easier to install than other throttle body, in that you don't have to transfer parts from your current TB to the new TB, and mess with voltages, etc etc. Install was pretty much easy; took all day because I installed Charge Motion Control Plates at the same time I installed the Throttle body. BIG difference in my Pony! Got the TB, charge motion control plates, cold air intake and custom tune and the "WOW factor" is through the roof! i LOVE it! money well spent!

    OK Performance Gains

    January 05, 2013

    Honestly didn't really notice any real performance gains. The only advantage was throttle response. Big difference in throttle response, it's much more responsive now. Installation, however, was a pain. Did not receive a template to drill TB holes. Had to figure out how to drill the holes myself. Ended up going to the hardware store and buying new washers and bushings so that i wouldn't have to drill such big holes. Eventually got everything to fit and line up properly. Just beware that installation may be problematic at times.

    Looks great and works great. If you plan on just in bolting and bolting on the new one. It won't, but it's really easy to drill out the holes to make it work.

    Not for Whipple Supercharged Applications

    August 01, 2014

    First, this would have received all 5s if it worked on my car. However, not listed on this site, but found elsewhere this item DOES NOT fit those cars with the Whipple 2.3L (140ax) Supercharger. The 180* inlet doesnt have enough tolerance between the S/C housing and the inlet to allow it to fit. The TB physically cannot fit on the inlet. AM did a great job in RMA and I've since purchased the FRPP 62mm one... Just a word to the wise for those with the Whipple S/C

    Shelby GT500 Ford Racing Throttle Body with Adpater Plate

    May 21, 2014

    My car is a 2006 Mustang GT. I installed this Shelby GT500 Throttle Body with Adapter Plate ( already correctly machined for correct fit ) in about 25 minutes and it is a true bolt on, plug in, and go part ! Excellent fit and finish and looks great in place of the stock throttle body. I also installed the Airiad Race CAI along with the SCT Bama Tuner and installed the performance tune ( it's idiot proof ) by simply following the screen prompts. This is the best combo of parts along with the tune to get the most bang for you hard earned dollars outside of getting into new heads, cams, or a turbocharger. I would recommend these parts and tuner to everyone with a 4.6L 3V engine. More sensitive throttle response and no lag between shifts in my automatic and it wants to spin the tires even with the TCB on and not even at WOT ! Best money I have spent for performance yet and I am still acquiring other parts for future install and tuner upgrade as well.
