    5 Top Rated Questions

    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.

    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.

      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.

      Low cost performance!

      For a low-cost performance upgrade this spacer is outstanding. There is a small improvement in throttle response and a 1 mile per gallon average improvement you fuel economy.

      Crackle! Tone! 1.5 MPG! about 7 HP gain!

      Definitely feel the difference and gain in power, plus gives your exhaust some extra crackle and tone. I am using this spacer with the MBRP Race cat back with SCT Unleashed tune and it pops very nice. I noticed MPG gains about 1.5 MPG, usually I get 25 MPG to college and back, after this spacer I get a round 27 MPG. You get better exhaust tone as well. I was then adding the CORSA down pipe and WOW! These all together turned my car to a 4 cyl beast. More crackle on deceleration, better tone, however, if you add down pipe with this MPG drops back to normal (I believe).

      Easy to install not much if any for power gains.

      Power gains small a little more lag between the hit of the turbo but it seems to hit harder.

      Increased Throttle Response

      Perfect fit, easy installation, and definite notice in throttle response! Did exactly what I'd hoped and expected. Only complaint is that the bolts for it are an allen bit and I wasn't expecting that. Lucky i had a small allen wrench to get the job done!

      Looks good but doesn't do much

      This product doesn't do much of what it claims to do. I've noticed no power or MPG gain from this product. It is also a pain in the butt to install.
