    Good 1st mod

    Installed as expected and described. I've notice 1 to 1.5 mpg bump. Can't tell if the throttle is really a little more responsive or if it's all in my head. Definitely worth it, though.

    Ask a Question

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

    YuryD

    • 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.

    can we get a retune for this spacer from bama?

    Mike

    • 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.

      Great

      It's not hard to install at all. I originally I had a check engine light appear because there was an air leak between the throttle body and the manifold. It was because I was missing a oem factory gasket that went behind the throttle body. Once I installed the gasket (I was missing), I was good to go. It definitely gave my stang a little more kick so it was worth it

      Steeda Throttle Body Spacer (15-16 EcoBoost) Review

      I purchased this piece because Steeda is known for their top notch quality and build. I was delighted to see this throttle body spacer in person just to appreciate the superior quality. It was super easy to install and even a grandmother can do it. I cannot tell for certain the exact gains from this unit as I installed a cold air intake at the same time. With that said, I can still report that my fuel consumption has increased with the addition of these modifications.

      bang for your buck

      I have to say I was sceptical at first but said screw it and bought the spacer...I gotta say I don't regret it....makes a subtle improvement on the low end of the rpm's but it makes a difference and you feel the response especially for the ecoboost ...I always bought a sprint booster with the steeda spacer...good combo for a budget MOD

      Package arrived with the spacer, 4 bolts, and 4 washers. Took me like 10min to install. I have only seen a slight increase in mpg. It was 25 and now it's always 26.6 mpg

      quick and easy upgrade

      This was a simple upgrade to install. I drive 80 highway to work as my mustang is my daily drivers. Recently finished a 1,000 mile road trip with my wife and bags of 4 days. Abient temps extending 95 and I averaged 32 MPG with a average speed with cruise and AC of 75 MPH.

      Very simple install but if you install it per instructions you can't see the Steeda logo! I chose to install mine upside down and it works great. Had trouble with the o ring fitting so I used black RTV instead. not sure about performance but with the BBK throttle body it works great.

      Worth the money

      The item looks as shows and performs as promised. I haven't seen the gain in MPG because I just got my new borla catback exhaust so I've been revving all day haha. However, revving doesn't make me lose as much fuel economy as before so that goes to show that it does help. Easy installation even with having to remove the head of my aftermarket roush CAI.

      Great product

      You do notice the difference once installed it's a great first mod easy to install and not expensive at all. Recommend that you buy it. What I have noticed is that it's accelerates quicker but as to more horsepower and torque haven't noticed any gains yet. And as better gas mileage haven't noticed it since I've only had it on for a week. Highly recommended if your looking for a cheap first mod
