    Maximize Horsepower and Torque Gains From Mods. After all the modifications you made on your Mustang, you should set your sights on upgrading the throttle body. The Ford Performance 70mm Billet Throttle Body is the final piece of the puzzle that would transform your tame street Mustang to a track speed demon. Moreover, this mod is compatible with your production air intake system.

    No Tuning Required. The Ford Performance 70mm Billet Throttle Body works well within the parameters of your factory tune. As such, you won’t need to recalibrate your computer after this installation.

    Tough Yet Lightweight Construction. This Ford Performance Throttle Body is manufactured out of premium billet aluminum for maximum strength without the extra weight. The surfaces are highly polished to prevent corrosion from eroding the metal.

    Complete Bolt-On Install. You can install your new Ford Performance Throttle Body yourself, as it’s a direct replacement of your factory part. New bolts will be included in the kit for a hassle-free mounting.

    Not Carb-Certified. The Ford Performance 70mm Billet Throttle Body is designed for competition use only. It should not be installed on cars for street use.

        The Ford Performance site says this fits 2015 to 2017 models. I am interested in this part, but am concerned whether or not it will fit a 2018 model.

        • From my understanding, this will fit all 2015-2018 Mustang EcoBoost models.

        In comments RonaldL says that also added a spacer to this body. Can yu say, what spacer will fit it?

        • The SR Performance Throttle Body Spacer is the only spacer we have confirmed will pair together with this Ford Performance 70mm Billet Throttle Body.

        Does the ford performance throttle body work with the steeda throttle body spacer?

        • The throttle body spacer is designed to only work with the OEM throttle body.

        Helpful (0)

        So I keep seeing that this won’t fit the 2018 ecoboost but that sound absolutely stupid since everything on the 2015-2017 and 2018-2019 cars when it comes to this particular part are exactly the same. What about this part makes it not compatible? Or are you not actually checking whether or not it fits? Because what it seems like is that several locations that sell this part simply have not updated their websites and everyone is going off of that as fact.

        • As Ford Performance still currently only lists fitment of the Ford Performance 70mm Billet Throttle Body for the 15-17 EcoBoosts, we do not currently guarantee fitment on the 18-19 EcoBoosts.

        Product description says not for street use. Why? Is it saying this cant be used for a daily driver? If so why?

            Worth the power

            No more turbo lag!!!!!!!! Love the hp. Gain and the loudest of the car.

            No more lag!

            This was such a simple mod! The car leaps now with no turbo lag at all. The only thing I can say bad is that my TBI had no Allen head bolts like featured during the install video. The quick fix to that is you can grind the shoulders off your four factory bolts and just barely reuse them. But worth every penny!

            Excellent Mod

            Was hesitant in purchasing but I’m glad I did. It does not add enough hp to make a difference, but it looks good under the hood. More importantly the response between the stock and this throttle body is night and day, very noticeable. Also these ecoboost can use all the help to deepen the sound, this will do that too. Recommend for sure.

            A Must Have!

            If you have any performance mods done, this is definitely a great addition. I installed this on my 2017 Ecoboost Mustang with the Ford Power Pack for the ecoboost Mustang, and the power gain is for sure noticeable. It even made my CandL BOV louder. It even adds a nice touch to the engine bay. Installation isn't that bad. Took me under an hour to install it. Overall, I am very pleased!

            I was waiting for a 70MM throttle body for my 2015 ecoboost. Finally ford performance comes through. And boy did they. Instant gains, very much different feel and response. With the wait.

            10mm matters

            I went from a 60mm to the Billet 70mm and you feel the difference
