      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.
