      Video Review & Installation

      Hey, guys, Adam here with Today, we're taking a closer look at and installing the BBK 85-Millimeter Throttle Body available for the 2013 and newer 5.7-liter Hemi and 6.4-liter Hemi Challengers. You should be checking out the 85-millimeter throttle body if you've got a lightly-modded or heavily bolt-on modded Challenger and you're looking to pick up some more airflow.Now, your factory throttle body is about 80 millimeters, so bumping it up to 85 is a pretty significant increase. Now, 5 millimeters might not sound like a lot to some of you guys, but 5-millimeter increase in size for your throttle body means you're pulling in a lot more air which can translate to more horsepower. One thing I will say is some guys think of a throttle body as a direct bolt-on that's gonna add power even if you're stock.I will say if you have a completely stock setup on your Challenger and you're increasing your throttle body size, it doesn't always translate to a positive. If you have a bone stock motor and you're going up 5 millimeters in size for your throttle body, it can start to be too much air for the mods that you have or lack thereof and actually cause you to bog down.I would recommend the 85-millimeter throttle body for the guys out there with 5.7 or 6.4 Hemis who have a lightly-modified naturally aspirated motor. Something that has a cold air intake, a cat-back exhaust, maybe some headers, some of those power adders that are looking to increase airflow.Sometimes that stock throttle body, the 80-millimeter one that comes on it from the factory, is a little too restricting. Some of those bolt-on mods like the cold air intake and exhaust require some more air to make a little bit more power, and that's when the 85-millimeter can definitely be a good upgrade choice.One thing I will say is it does not require a tune. A tune is definitely recommended. Anytime you add these bolt-on mods, adding a tune, especially one for 93 octane, can really increase that maximize the potential, but again, not required, something I do want to point out. This is made from a 356 aluminum housing and we'll get a little bit more into the details of the construction here once we have our factory one off of our Challenger. Behind me is our 2013 RT and again, it fits all 5.7 and 6.4s, so this is the one we're working on today.I'm gonna show you guys step by step how to uninstall that factory 80-millimeter and install our BBK 85 in just a quick second. If you guys want to pick this one up for yourself, you can do so for just about 480 bucks, which is a really common price tag for these aftermarket throttle bodies, especially ones that are increased in size for performance benefits. Now, as far as that install, I'm gonna give it one out of three wrenches on our difficulty meter. Anybody can tackle it with very, very simple hand tools.I would recommend having a flathead screwdriver on deck, very simple socket set, a simple ratchet. An impact gun can help, but it can be a little difficult to reach some of those bottom bolts on the throttle body with an impact gun. Having those ratchets on deck will make all the difference. With that said, an hour maybe a little bit less if you have some experience with this, pretty simple stuff, I'll take you guys through all the steps, so let's get to it. The tools used in this install include a flathead screwdriver, a ratchet, small extension, and an 8-millimeter socket.Step number one here, of course, pop that hood open and there is an engine cover on our 5.7, so we're gonna pop that off and out of the way. That just unclips. We can set that aside. All right. Now here's our throttle body right here in the dead center, connecting our intake manifold to our factory intake. What we're gonna have to do before we unbolt anything is disconnect our sensor harness from the side here. That's got that red locking tab, and I'd suggest grabbing a flathead that can just pry back on that locking tab. Give it a good pinch and it'll pull straight back.Just tuck that out of the way. You can wrap that right around the oil funnel. Set that aside. There is a couple of bolts holding this on. There's two up top and two underneath. But before we remove those, we're gonna loosen up the clamp on our factory intake and that'll allow us to pop this off, giving us better access to those bolts. All right. Next step, grab your flathead screwdriver and we're gonna loosen up the clamp on our factory intake connecting to our throttle body. If you have an aftermarket intake, it might be in a different position on the opposite end. Of course, either way, that'll just help us pop this straight off.Now, there's an extension bracket down here and you can just pull straight up on that and it'll pop out of position and give you a little bit more room to work with. Now, if you wanted to completely remove this, which, of course, can be very helpful, there's one more of those clamps on the opposite end and we can pop this whole thing out of place. Now we can just set this aside.There is another sensor on the opposite end here, but it's not really necessary to unplug that. You can just set this off and give you full access to the throttle body. All right. Now, we can grab our 8-millimeter socket here and just back out these four bolts. Again, there's two on the top and then two underneath. Having this air intake completely removed and out of the way like we just did gives us better access to these bolts.You want to set these aside because you will be reinstalling them with your new BBK. With those four removed, let's pop this right off and set it aside. So, we finally got our factory throttle body off of our 5.7 Hemi and on the table here next to that 85-millimeter option from BBK. As you can see, not too, too much to talk about here when comparing the two. Biggest difference is this is 85, this is 80-millimeter, and you can see a slight difference in size.Again, 5 millimeters on paper doesn't sound like a lot, but this can make a huge difference to the airflow to your intake manifold. One thing I do want to point out is this is forged from a 356 aluminum housing, making sure that that's durable, long-lasting, and optimized for flow through air. Pretty similar to the factory construction here, so not too big of a difference there. I will say this does look a little bit better with the BBK stamped metal right on the top here, that BBK power plus 85-millimeter logo.One other thing I want to point out is, as you can see, this does come with an actuator and the sensor already attached to the BBK. That is not the case for some other aftermarket throttle bodies. Sometimes you just get the throttle body housing itself, sometimes you have to take apart your factory throttle body to transfer over the actuator and you'll be messing with springs internally and that can be somewhat of a mess dealing with other aftermarket options. The BBK, not the case here, it's a very, very simple bolt-on.So, like I said, not too, too much to talk about here, big difference in airflow with this particular one. We are gonna reuse our factory gasket. Now, one thing I do want to say is some of you guys might take your throttle body off and the gasket will already be stuck to the back of that factory throttle body. You can just peel that right off. Other guys, it might actually be left in the open hole on your intake manifold. You can leave that there if that is the case, but ours came off on the back of the throttle body, so we're gonna take it off and reuse it. If it isn't in very good condition, this is a great time to pick up a new gasket, very important component here.If it's ripped, falling apart, it looks like it might be ripped in the near future, just pick up another one. You don't want any air leaks that can throw a check engine light, can very much hinder performance, so big critical thing here. We are gonna reuse the four factory bolts like I said. We're reusing this gasket, it's in really good condition. Ours is a 2013 RT, relatively new within the past five, six years, so good condition. Let's go back under the hood and install this. We'll first start with that gasket.All right, so as you can see, our factory manifold here has this lip around here. That's the seat for your gasket. You can grab that gasket, doesn't really matter which side you put inward. We're just gonna line that along the inside of that lip. That's gonna allow the gasket to have a proper seat and we don't have to worry about it coming off or being open at one end or not fully sealed. That's completely sealed in there, you can push it all along.Grab your BBK throttle body, it's time to bolt it up. Line that throttle body up with the bolt holes, use those factory screws. It's a good idea to just tighten it down by hand at first just to make sure it's all lined up. Grab that ratchet, get it started, just a couple of threads. Same thing on the bottom. All right. Once you have all of them started and you know it's in the right spot, grab that ratchet and tighten them all down. You don't want to overtighten them and strip them out, so just get them nice and snug. One little extra half turn and then you're good to keep moving on.Next step here, let's put that intake housing back on. We're gonna connect it back here at the air box first. Makes life a little easier, and you can see it's got a little notch, it just seats right in there. Grab your flathead and tighten down that clamp. Once you get that nice and tight, can we move on to this part. Wanna get this snapped over the throttle body. All right. Once you get that nice and snug, make sure you pop this back onto that extension bracket. That'll hold that in place, grab your flathead and tighten this down again. The last step of the process, that factory harness that we set aside earlier, can wrap that back around, wrap this around the front, plug it in. Once it snaps into place, you'll hear that click. Push down on that locking tab. At this point, once you have that sensor back on, the last step, we'll just throw that engine cover back on, shut your hood, and you're good to go. Well, guys, that's gonna wrap up my review and install for the BBK 85-Millimeter Throttle Body. You should check this out if you're looking to boost up some of that airflow to your intake manifold with a slightly larger throttle body opening. You can pick this particular one up right here at
