      Video Review & Installation

      Justin: If you're looking for an easy bolt-on modification to increase the airflow in your 2018 and newer Coyote-powered GT, then BBK's 90-Millimeter Throttle Body here might just be for you. Now, the BBK option that we're talking about today will not require the use of a tune, but will incorporate quality CNC'ed aluminum for the build, mixed with factory Ford electronics, all for right around that mid-$500 price point. Now, since this simple four-bolt install is pretty basic stuff, the site's going to call this a pretty soft one out of three wrenches on the difficulty meter, and about an hour or less to complete from start to finish. But, if you hang till the end of the video, we'll show you how it's done.So, if you didn't know, BBK has been a prominent name in the Mustang game ever since brothers Brian and Ken picked up their first Fox-body back in the '80s and started producing parts to make it a little bit faster. Fast forward to today, and their support has only grown for the Mustang, producing parts for just about every gen under the sun, now including the new Gen 3 Coyote found in the 2018 and newer GTs. So, the 90-millimeter throttle body that we are featuring here today is going to be a pretty substantial bump in size when compared to the factory 80-millimeter throttle body located on the stock GT. And I know 10 millimeters might not seem like a huge difference, but in the world of throttle bodies, it is pretty significant. Now, full-disclosure, guys, I would typically recommend something of this size strictly for forced induction applications or all-out NA builds. And while I still would technically kind of lean in that general direction, for most owners out there, I will say the increase in airflow, along with the increase in compression for the 2018 and newer GT, will make this somewhat relevant for even mild bolt-on setups.Now, as far as your build and construction is concerned, well, listen, guys, these things are built and assembled right here in the USA, using some high-quality stuff. Now, I've actually seen these things start off life as a chunk of aluminum before being CNC'ed down to the basic throttle body shape that you see here today. After that CNC process, BBK does hand-build everything, tops them off with factory Ford electronics, which is not only gonna make for a simple plug and play install, but best of all, you're not gonna have to worry about chasing any crazy electrical gremlins due to some third-party internals or electronics. Now, on top of that, guys, BBK claims that no tune is required in order to run their throttle body, although the site will certainly recommend one, to get the most out of your setup, and that's really gonna be entirely up to you at the end of the day.Now, as far as your basic benefits you can expect here, well, I would think the obvious expectation will be a little bit more power, depending on your mods, along with a little bit more throttle response to boot. Now, you can also look forward to a factory fit, but keep in mind, due to the larger opening here of the throttle body itself, making the factory or aftermarket intake coupler go on might just be a little bit more of a challenge, so just be prepared for that prior to the installation. BBK does also kick in some new hardware here to help you out with that. But overall, guys, again, a very, very simple job. In fact, to give you a better idea of how this is going to go down, here is that detailed walkthrough we promised you, in addition to a quick tool breakdown.Man: Tools used for this installation, a 3/8 drive ratchet wrench, 15-millimeter socket, 10, 8, and a 5-millimeter Allen key socket, extension, flat-head screwdriver, channel locks. Optional is an impact. All right, so the first step is obviously getting underneath our hood. All right, so what I'm going to do first is remove our strut tower brace so we can get this engine cover off. What we have to do is remove our little battery cover here. You may have a push pin here. Ours is missing. So, just get that out of the way. Remove this little loom holder. This is a 15-millimeter nut. Set these off to the side. Get the other side off. All right, you're also gonna have some covers protecting your 10-millimeter nuts, holding your engine cover on, so pop them off with a trim panel removal tool or a flat-head screwdriver, and then use a 10-millimeter socket to remove those nuts, and then lift up.All right, what we're gonna do next is remove some of these PCV hoses and the sound tube hose from this elbow. We're also going to remove the elbow, to gain easier access to that throttle body. So, I have a pair of pliers here. Let's remove the sound tube. Remove this as well. For these clips, you just pull back on that plastic tab. All right. Now let's release these hose clamps for our elbow. All right, so what we're gonna do next is disconnect our throttle body. I'm gonna pull back on this red tab, then depress the connection there and pull back. Now we're going to take an 8-millimeter socket and remove these four bolts. We will not be reusing them. The kit comes with new bolts. All right, I'm gonna pull this throttle body off, and bring our new one in. So, what we have to do is actually attach this little adapted, as we are doing the 90-millimeter throttle body. So you can see that this is tapered in to help that airflow. And I'm going to put two bolts through the hole, to help hold that spacer in place.Then we can put it on the intake manifold here, and just start those two bolts. All right, now we're going to take a 5-millimeter Allen key socket and tighten up these. All right, now we're going to make our connections, starting with the wire connection here. All right, now let's put our intake elbow back on. Let's start over here by the air box, make sure that's seated. And this may be a little tight to get back on there, but it will fit. All right, so what I'm doing here is I'm taking a flat-head screwdriver and getting behind our coupler here. Just be careful not to gouge it or rip it. So, with that on, let's tighten down this hose clamp, make sure it's in those. Take the flat-head screwdriver and tighten down this clamp. Let's tighten down this one as well.All right, let me get my pliers and reconnect our sound tube to our intake elbow here. And let's reconnect all of our PCVs. There's one in the back and there's one in the front. Once you have your intake elbow on, everything secured, including your PCV hoses and your sound tube, we're gonna put our engine cover back into place. Let's get our nuts back on here. If you're using an impact, make sure it's on the lowest setting. All right, now we're going to put our strut tower brace back on. You wanna make sure you go underneath that loom, and then connect this side. Install your battery cover.And that's gonna wrap up my install of the BBK 90-Millimeter Throttle Body. And for all things Mustang, keep it here at
