      Hey everybody, I'm Justin with and this is my detailed look at BBK's 85 and 90mm Throttle Body options fitting your 2015 and newer Mustang GT. The BBK throttle body options are going to be for any S550 GT owner out there who is looking for every last bit of power out of their naturally aspirated or forced induction five liter setup. Let's face it guys, your motors are essentially glorified air pumps. Their job, to move air in and out as quickly and efficiently as possible, making you go faster in the process. Now certain parts will help your efficiency more than others. For instance, a set of long tube patterns will be a little bit more beneficial in the quest for big power than say an aftermarket axle back exhaust system for instance. But both are going to be critical when you start making some big power. That being said, a throttle body is going to be one of those parts that's not going to make a ton of power on its own, but will be beneficial when the quest for more power starts getting a little bit more real. The factory GT throttle body is 80mm, guys. So BBK is giving you the option of stepping up either five or ten additional millimeters in diameter, depending on your application. Now a quick rule of thumb, I always like to recommend the 85mm option for naturally aspirated setups. While the 90mm option would be a perfect addition to any forced induction setup, whether you're going centrifugal blower or turbo application.Breaking down the construction a little bit, guys, here's what you're going to be looking at. Now high quality, 356 grade CNCed aluminium for pretty much the entire body. We were lucky enough to take a tour of the BBK facilities down in southern California. We've seen how these things take shape, and let me just tell you, it's very impressive. The throttle body essentially starts out life as a hunk of aluminium and then it's CNCed down to the final product you see here. One thing I do want to point out, BBK utilizes Ford OEM electronics for their drive by wire stuff, everything is pre-wired, ready to go, plug and play application here. You're not going to have to worry about a third party electronics or anything goofy with that. Now this is a no tune required part, meaning guys you can plug this thing in and go without the use of a custom tune. That's never a bad idea, that's always going to maximize your potential. Comparing this price-wise to other options on the market right now is kind of tough, because honestly, there's not a lot available for the S550 GT. That being said, you're going to be dropping around 500 bones for the BBK throttle body option, which might seem a little steep for some of you guys at home. But when you're trying to squeeze every last bit of power out of your setup, you have to pay to play. Switching gears to the install here, guys. Very simple stuff. You're looking at a one out of three wrench job, on my overall difficulty meter. Maybe 30 minutes to an hour in the garage or driveway to get everything knocked out. Basically if you're a first time wrencher out there, don't be afraid of this one. Only four bolts holding the throttle body onto your intake manifold. So grab yourself a basic socket set, a few extensions, and a flathead screwdriver to remove your intake from the actual throttle body. You're not going to have to totally remove the intake from the car, but just enough so you can gain access to the four bolts here. BBK does include brand new hardware for the new throttle body. So again, remove that factory throttle body, reinstall the new BBK in reverse order, and you should be good to go. All right guys, to wrap this one up here. In my opinion, a throttle body shouldn't be the first place you go in looking for more power out of your ride, because honestly, there are more gains to be had using different modifications for around the same price point. That being said, once you tackle all those basic modifications and you are looking for more power, an aftermarket throttle body from BBK will help you achieve more power through your naturally aspirated or forced induction setup when compared to your factory throttle body. So to learn more about the BBK options for your ride, be sure to check them out right here at

        Did better than expected

        I install it and done the learning on it with the car, took it for a short drive, on the way back I had to see what she would do, so I stopped, well I'm here to tell you the was a difference, on the stock I had a throttle body spacer, well it did a faster take off with the 85mm than it did with the 80mm and the spacers.

        Noticable Difference

        I installed the BBK 85MM Throttle Body on my 2015 Mustang GT premium package 6spd manual. Since I have the factory 3.73 gear package with the premium, the low end on this car was already pretty impressive. However, it seemed to fall on it's face a little when shifting to 3rd gear at high RPM. The throttle body really made a difference in this area. Noticed much more throttle responsiveness and quicker acceleration to rev limiter. I have since done a resonator delete, H-pipe, and BAMA 93 Octane tune. Really happy with the acceleration, throttle response, and top end. Was considering forced induction, but pretty content......for now anyway. The throttle body was about a 1 hour job and was extremely easy. Quality product with Ford electronic components.

        Enhanced Performance

        Just installed the BBK 85mm 1806 on my 16 Mustang GT. Already had MRT H-Pipe, Ford Racing Touring axlebacks, (made by Borla) Airaid intake tube and a KandN oiled filter. Also had loaded Ford Performce pack 1 tune. I stall was not difficult, the only exception was the plug for the throttle body. Tip: Pull the red locking tab, then look on the backside of the plug for a small black tab. Gently pry it up with a very small for screwdriver. This is the locking tab. Once slightly lifted, the plug will come out easy. I hooked up the negative battery cable and started the motor. No idle issues, but followed the re-learn process. What I noticed, was increased throttle respond and overall a sense of eagerness the way the motor resonded to throttle movement. Motor feels stronger through the gears and the power increase is noticed. AFR is unchanged, 13.8-14.2 in 6th gear cruising, (have been monitoring) and compliments the tune previously installed. A bit pricey, but you get what you pay for and if you're on the fence and setup similar to how I am, go ahead and buy this throttle body. You will be pleased as I am with the upgrade!

        Worth the money

        You get what you pay for. I pulled the 87mm that just couldn't be tuned to eliminate surging. The 85mm worked like a dream. Anybody want an 87mm?

        Very happy with this. Easy to install and seemed to help with a bit of low end pep. Set up and learning sequence was easy and seems to run flawless.

        Better then 87mm

        Sold my 87mm due to it requiring and difficult tune to run. I’m really liking the 85mm it’s no tune and huge difference with a tune. Definitely worth it just very pricey.

      i have a 2017 GT premium convertible i am looking at a cold air intake from roush (as well as the rest of the goodies with the stage two kit) will the typical roush tune with the cai change anything or should i be good to go. also will the Roush Cai fit with this as it is aftermarket? thank you!

      • You are able to use this aftermarket throttle body with the Roush stage 2 kit. Since this throttle body doesn'trequire a tune, you will not need to update the tune with Roush. However, we would recommend a tune update to get the best performance with your upgrades.

      Can I still use my throttle body spacer with this product or are spaces just designed for factory throttle bodies?

      • We do not recommend installing aftermarket throttle body spacers with an aftermarket throttle body as spacers are designed and fabricated to work specifically with the factory throttle body. Customers have experienced issues installing the two components together.
