      Video Review & Installation

      Justin: The BBK 85-millimeter Throttle Body here is going to be for the '11 to '14 GT owners who are looking for every last bit of power out of your naturally aspirated or boosted 5-liter V8.Now, materials for the no-tune required CARB-certified part will be that 356-grade aluminum for the body itself along with your factory 4 drive-by-wire electronics, all for right around that mid $500 price point.Now, install is gonna be a breeze for most owners here, so figure one-out-of-three wrenches on the difficulty meter, maybe an hour at most to complete from start to finish. But hang with me for a bit guys and we'll show you how it's done later in the video.So throttle body upgrades continue to be a popular choice for both car and truck owners alike because they're an easy way to add a little bit more top-end power and a little bit more throttle response but without the need for any tuning or additional modifications. Now, your factory 5-liter GT throttle bodies coming in at 80 millimeters while the BBK is gonna step that up 5 millimeters to, you guessed it, 85 millimeters.And that's gonna result in roughly a 15% increase in airflow capability. Now, with all that said, guys, I want Gen 1 owners to be realistic here when we're talking about gains. Now, I would say the best-case scenario for most naturally aspirated owners probably be in that high single-digit, low double-digit range without the use of any tuning and maybe a little bit more on your forced induction applications.Now, as far as your construction is concerned, guys, well, you are gonna be looking at a very high-quality piece of 356 aluminum for the actual body itself. You got the really clean BBK logo etched on top to give things a subtle nod that you're not necessarily looking at a stock part here. Now, on top of that, the BBK throttle body does receive OEM dye-stamped throttle linkages, double-sealed bearings, and are loaded with completely new factory Ford electronics.They've already been calibrated, meaning you can bolt this thing up and go without needing to do anything else. But I do wanna briefly go back and talk about that ease of install, right, because that is a big factor when choosing a mod such as this. And you're looking at a very simple four-bolt job here.BBK does include some longer bolts in the box, guys, so this should be a very straightforward day in the garage or the driveway. But now to give you an even better idea of how this one will go down on your Gen 1 coyote at home, feel free to check out our detailed walkthrough and tool breakdown now,Man: Tools used for this installation, 3/8 electric impact gun, 3/16ths Allen head socket, 1/4-inch drive extension, 13/8-millimeter sockets, 1/4-inch drive ratchet, pliers, and a flat blade screwdriver.Hey, guys. I'm gonna show you how to install our BBK throttle body on our '14 Mustang. So let's get started. First thing we're gonna do now that we have our hood up, we're gonna disconnect our negative battery cable, and then we'll remove our strut tower brace and our engine cover.First thing we're gonna do is we're gonna take my 1/4-inch driver ratchet here with my 8-millimeter. I'm gonna disconnect the negative battery cable. So now we're going to remove our 13-millimeter nuts right here, and we'll remove these two with our 3/8ths gun and our 13-millimeter socket.Now, you're gonna wanna just repeat that same procedure and remove the other two nuts on the other side. So now that we have our four 13-millimeter nuts removed, we're just gonna grab our brace, lift it up, and remove it. Now, we're gonna remove our engine cover. You're just gonna wanna lift up on it, give it a nice tag, and remove that out of the way.Now, that we got our cover off, we're gonna remove our PCV hose here. All you're going to do is push down on this clip and pop it right off and get that out of the way. Next, we'll take off our air tube here. I'm going to use my pliers, pull on to the tube, and remove that off of our intake tube and just get that out of the way for now.Next, we'll take a flat screwdriver and remove our two hose clamps. Now, I'm gonna take my flat screwdriver to loosen up these two hose clamps. That way, we're gonna remove our air intake tube.Once we have those loose, we're just gonna give our tube a pull and remove our intake tube. Now, that we have air intake tube off, we're going to remove our electrical connector here. And then we're going to take our 8-millimeter and remove these four bolts holding the throttle body on.So first thing we're going to do is remove our electrical connector. And we'll pull back on this red clip, push in, and pop our electrical connector off. Next, we'll take our 8-millimeter on our 1/4-inch drive, and remove our four bolts holding our throttle body on.With those four out, we can just remove our throttle body. And then what we'll do is we'll take a rag with some Carb Clean or some injector cleaner, and we'll just lightly clean this up to make sure our surface is clean. Now I'm gonna take my microfiber with some Brake Clean, and I'm just gonna go over and wipe our surface here to make sure it's clean.And now, we'll get ready to install our new throttle body. Now, I'm gonna take our new throttle body with our Allen head bolts that were supplied in the kit, and I'm gonna install this onto our manifold and get this started.Now, once I got them all started, I'm going to take my 3/16ths Allen socket on my 1/4-inch drive and tighten them up. First thing I'm gonna do is snug them all, make sure the throttle body is straight. Then I'll go around and give them a tight.Now, that we have those tight, we're going to install our wire connector. Once we get that in place, we'll push our red clip in. Our throttle body is tight and it's on. Next, we're going to install our air intake tube onto our vehicle. We're going to install our air tubes and then tighten up our hose clamps. This is a little bit bigger, so it might be a little bit more trickier to get this started overtop of the throttle body.Once we have that in place, we're gonna slide the PCV hose back on, make sure it clamps. Take our pliers, compress our clamp here, push it on in place, and we'll tighten up with our flathead to those clamps.Next, we'll install our engine cover and then our strut tower brace. Now we'll install our engine cover back into place, just give it a good smack. Next, we'll install our strut tower brace and put that back in place, and then reinstall our 13-millimeter nuts.I'm gonna take my gun, my 13-millimeter, and tighten all of them back up. Last, we'll install our negative battery cable. So now, we'll install our negative battery cable, tighten this up with our 8-millimeter socket and 1/4-inch drive ratchet, and that wraps up under the hood of our installation.So now that we got our new throttle body in place, there's going to be a learning process for the throttle body. And what you're gonna wanna do is you're gonna wanna make sure your vehicle is in Park or Neutral. And then with the parking brake on, you're gonna wanna start the vehicle and let the vehicle run for about four to five minutes, get it up to normal operating temperature. And then you're gonna want to let it idle for about a minute or two just like that.Then you wanna go and turn your AC on. Let it idle again for a minute or two. And then you're gonna wanna drive the vehicle for a little while to make sure that the throttle body and everything and it learns it's idle. That wraps up this review and install of our BBK 85-millimeter Throttle Body for '11 to '14 Mustang GTs. Thanks for watching. And for all things Mustang, keep it right here at
