      Review & Installation Video

      Hopefully the mic's on.So, switching gears to the installation portion of the video. In this video, I'm going to give a quick overview of who this throttle body's going to appeal to, the instruction and materials used by BBK, what this is going to do to your wallet, and then what it's going to take to get this onto your car. I'm going to be giving this an easy, one of the three wrenches on the difficulty meter and about thirty minutes, and I'll have a little bit more for you on that later.So if you're the owner of a 2015 through current S550 EcoBoost and you're in the process of opening up your intake side, or if you've already done so, and you're looking for some other modifications, this is going to be a good option for you. The BBK 65mm Throttle Body that I have here today is going to be for the EcoBoost owner that's not too into the idea of picking up a throttle body spacer and for someone that's looking to gain horsepower, torque, better throttle response, as well as creating some noise from the hood, as well as for someone who doesn't want to pick up a handheld or custom tune.So if you're looking for a throttle body for your build you may already be running some of the supporting mods but you get a colder intake on the intake side or downpipe on the exhaust side, and the throttle body's going to be a great modification if you do have some of those supporting mods. Now, a throttle body isn't going to deliver the same amount of improvements on a bone stock car as you might find with a car that does have supporting bolt-ons. And BBK is going to be claiming eight to twelve horsepower here but that number can fluctuate depending on the supporting modifications you might have.If this is your tenth Mustang or your first, you've probably heard of BBK at some point or another. These guys have been around for about 30 years now and they know exactly what they're doing in terms of performance parts. Now with that being said, we're going to be see that BBK is going to have this manufactured out of a 356 grade aluminum, that's going to be CNC. Additionally this is going to come equipped with brand new drive-by wire components.Taking a looking at the price here, you should expect to be spending about $500 bucks for this throttle body. At the time of shooting this video, there aren't too many other options available in terms of full replacement setup. There are going to be some throttle body spacer out there but I wouldn't expect to be picking that much in terms of horsepower or torque, as it's not going to be a full replacement setup.Switching gears to the install portion of the video, you're going to be looking at a very easy one of the three wrenches in the difficulty meter and about thirty minutes to get this onto your car. So looking ahead, some things I'd make sure to have on hand would be a full socket set, a couple screwdrivers, and a little bit of patience. But to start, you're going to want to crack your hood, remove your battery cover, then disconnect your negative battery terminal. To begin, what you're going to want to do is loosen the clamp on the air inlet tube and then begin to pull that out along with the filter, and then you can simply swap out your new throttle body with your supplied hardware and you're good to go.So just to wrap things up here, some final thoughts. If you're the S550 EcoBoost owner, you're looking to improve your airflow and reduce some turbo lag, pick up some horsepower and torque, as well as give you a little bit more noise under the hood, we'd definitely recommend you checking this out for your built. I'm Alex, and for all things Mustang, keep it right here at

        Feels Like My Tune Doubled

        Absolutely insane power gains from this simple installation. Honestly I did not want to spend the cash but I am SO glad I did. The car is so much more responsive and fun now, especially having a tune to back up the extra power. Sounds incredible when you turn the car on and I've noticed the car heats up quicker! I usually wait till the RPM's are under 1,000 until I actually throw the car in drive and go, and with the throttle body they get under there in like no time at all! Oil gauge heats up way quicker too! Amazing purchase and very happy with this mod!!

        Surprisingly good

        I had this for a long time and took forever to install it because I figured it wouldn't do very much. Boy was I wrong. I was immediately surprised at how well this made the car perform; it is much smoother and acceleration is faster. Seems to have helped with turbo-lag; it really seems like the car was starved for air before. This thing totally surprised me and I love it. Only reason I gave it four stars is that it looks like Ford Performance has come out with a 70mm now.

      The description says " Not legal for use on pollution controlled motor vehicles; intended for off road use only." So if I did this mod and drove it on the streets, I assume the EPA could come after me, just like "if" I were to do any mods to my Harley and drove it on the streets, they could come after me for that, as well. ;)

      • This would not be legal in the state of California or other pollution controlledstates and they would be able to get you if you get checked.

      will this decrease the efficiency of my gas mileage at all?

      • Like with all performance modifications, being they increase the horsepower/torque of the vehicle. There is a chance that you may see a slight decrease in your mpg. With that being said, the decrease is very minimum and honestly depends on how the vehicle is driven.

      I have added Roush Level 2 mods to my 2017 Ecoboost, (axle back exhaust, intake and Roush tune). Will this throttle body improve performance further? Will it void/effect the Roush tune?

      • This throttle body will help improve your Ecoboost performance! This addition would not affect the Roush tune that you have currently with your Ecoboost and will not require a new tune when installed.
