        Very nice

        The polished looks really spiced up the engine compartment. Performance is great. It also gave me .4 mpg increase. Well as long as I don't race around.

        5 2016 EcoBoost - DisplayName88 Installation Time: Afternoon

        Nice, Easy Upgrade

        It took more than an hour because I added an extender too. I had to order the right length socket head cap screws from McMaster after I couldn't find them at the local hardware store. The performance gain isn't huge, but the throttle response and sound is nice.

        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!

        5 2016 EcoBoost - WhiteStang75 Installation Time: Less than 1 Hour

        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.

      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.

      Can this be fitted along a C L cold air intake?

      I was wondering how much of a horsepower increase one might get with this throttle body.

      In a previous answer, you said this throttle body is not compatible with the SR performance spacer. In the video on this listing, you say that this spacer is compatible and will work with this throttle body. Will this throttle body work with my spacer or no?

      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. 1 answer
