        About how much horse power will the Steeda Throttle Body spacer add to the 2017 Ford Mustang EcoBoost?

        • You shouldn't expect to much horsepower out of a throttle body spacer but more of an enhancement in the throttle response. However, you can expect around 5 additional horsepower once installed. You can potentially expect more with an optional tune.

        Helpful (4)

        can we get a retune for this spacer from bama?

        • You can request a new tune from Bama for this spacer. But it is not necessarily needed. The spacer is simply changing how the air is flowing. It does not change how much air flow you are getting.

        Spacer vs. BBK Throttle body. which will be better? pros and cons?

        • The Steeda Throttle Body Spacer will provide some gains, however it will still be limited by the stock throttle body. The BBK Throttle body will provide larger gains by increasing flow over the OEM throttle Body.

            Worth the effort

            I just installed this Steeda Throttle Body spacer in my 17 EBoost Mustang. I believe it did improve throttle response - particularly at low end, and I think I hear a difference in intake sound. I haven't driven it enough to conclusively comment about gas mileage, but others claim improvement. It is a very nicely manufactured piece and looks good in the engine bay. Installation is straightforward and I think it is worth the effort and modest expense.

            Easy install! Instantly could tell a difference in Throttle response and can see the gains in MPG. High recommend.

            Great But

            To tell the truth I have not felt any more Power in my car but this product associated with a Manifold spacer adds more power at midrange. And have not noticed a real gain in my MPG as it might be a very slight gain. Installation is pretty easy the only problem is you have to remove your Air Intake if you want to be free when you fit the spacer

            Works Great

            The spacer does fine drove the car around for a day or two before testing the true long drive experience on the open road. went from 37mpg to 40mpg with a fresh set of spark plugs installed. Highest I got was 41 mpg on the flat plains.

            Steeda Throttle Body Spacer

            Pretty straight forward on the install. I took my car out for a spin immediately , mind you I installed the KandN drop in filter as well. Noticed an immediate difference as far as throttle response. Definitely picks up and goes much faster and its definitely noticeable in those lower RPM's.

            Super

            Great Product a lot of people say they don’t feel anything it’s not worth it but I would say otherwise it is worth it for being cheap and I do feel a little bit of more exhilaration and throttlebody respond thanks American muscle

            Doesn't really do anything

            Had it on for a week. Was hoping for better mpg after reading other reviews but everything is the same. Got it to drill and tap a boost reference for synapse and it works great for that because the vacuum line is vertical as opposed to the BRA that is horizontal, and it's the same price as the BRA, so I'm happy.

            Bad quality

            I order twice because I don’t believe its quality is as bad as this. There is so many burr inside of the spacer. Steeda didn’t cut it very well and then no body check it before selling.

            Wingnut's review

            As I said with the pic. Jury is still out on any changes in mpg, or hp. A slight improvement with throttle response does seem agreeable. A very easy install.

            Excellent Product

            Super easy to install. have had no problems with the product. I've seen slight gains in power and performance gain, as well as a slight shift in tone in the sound. It is slightly lower and more rumbly.
