      Video Review & Installation

      Jake: Jake here for American Muscle, and today I'm taking a look at this AFE Silver Bullet Throttle Body Spacer for 2008 and newer Dodge Challengers with a 5.7, 6.1, and 6.4 liter Hemi engines. If you're looking for a simple mod that can increase your throttle response and your overall enjoyment of your Hemi Challenger, then something like this throttle body spacer from AFE might just be the right upgrade for you. Now, let's set the record straight right off the bat here. If you're looking for big power numbers or a big increase in your miles per gallon, a throttle body spacer like this is not gonna provide you that. While you may feel a slight increase in performance, throttle body spacers typically do more for the experience of driving than anything else. The idea here is to increase air flow and mitigate some pressure within your intake manifold by effectively increasing the length of that intake, and thus the volume of air that it can hold. When an intake valve closes, it can send a high-pressure wave back up through the intake manifold. We figure those intake valves are closing rapidly, hundreds of times a second, and when that happens, it's gonna create some pressure within the intake manifold. So, having this albeit small additional space can help relieve some of that pressure, resulting in better overall air flow and lower pressure within the manifold, which is what you want. Adding a spacer creates, again, just that, some additional space, and it's going to effectively lengthen your intake manifold. Lengthening that manifold also typically yields better throttle response, and since this isn't something that moves, making it a passive device, it's gonna give you consistency and it won't use up any additional energy from your engine. Now, there are a few schools of thought as to whether or not smooth flow or turbulent flow is going to yield the best result when it comes to throttle body spacers. Now, AFE has taken the turbulent approach as you might be able to see here, using what they call a serrated helical pattern. Now, the idea is that this is going to stir up the air molecules into a sort of hurricane pattern, which is gonna help with the air flow mixing process. AFE claims that this pattern will also help decrease the amount of whistle that some spacers can create under throttle, so it's not going to be as intrusive as some others in the markets might be. And the whole thing is machined from 6061 T6 billet aluminum, so it's high-quality, high-strength, light-weight, durable and heat-resistant. Now, as far as price goes, this is gonna run you just under $200, which is pretty much the top of the category as far as throttle body spacers are concerned. However, you are getting a very high-quality piece here and you can see that as soon as you open the box. It also comes backed by AFE, which is one of the most reputable companies when it comes to intake products. Now, that brings us nicely to the install. Coming in at an easy one-out-of-three on our difficulty meter, this is a simple installation process that should take you about an hour or less. It does include... New longer bolts are included in the box, and be sure to check out the guide that comes with it to make sure you use the correct bolts for your engine. You also get a new gasket to replace your old one, which is a nice touch as well. It's a pretty straight-forward process that you can easily accomplish at home. The only tools needed are a flathead screwdriver, a ratchet, and a small socket set. And to show you just how to get it done, here's one of our American Muscle customers installing it on their challenger.Man: Eight millimeter socket. Gonna remove... [inaudible 00:03:08] first. [inaudible 00:03:39] Tomorrow we'll get everything [inaudible 00:03:47] here. I'll unhook the plug back here and take everything out. You can see I put a shirt down in here, because if I dropped anything, it wouldn't fall down on that [inaudible 00:04:19], because there's cover on it and you can't get anything out of there. So... And we'll unplug this guy. Okay. Next step is to remove the bolt. [inaudible 00:04:38] Right. Okay, let me go get those other parts and I'll be right back. Hey, we're gonna finish removing these. Again, I'd loosened the bottom up all the way. Kind of just wanna pull them out together, because I don't want those bolts falling. So, voila. Shouldn't be on here too tight. Throttle body off. Was an older one. This is the new one I'm gonna put on. Okay, here. I got the directions here, and if you can see, they [inaudible 00:05:24] a bag of bolts. So, you need to pick out the right ones for your car. So, 11, 6.4, use number 12, self-threading, which is right here. So, it's these guys. They're a little bit longer than the other ones, because the spacer is really thick. See how thick that is? Okay, and then we have the gasket. Goes in-between this throttle body. And the spacer. Make sure air goes in the opposite side. And I'm thinking it might be easier to try and get a bolt in there. Keep everything lined up. I'm not a mechanic. I'm an excavator, so bear with me. I'm just thinking it might help hold everything together. Not much room down in here. Just getting started on [inaudible 00:06:29]. All right. Just let that hang. Don't wanna use my battery to get them started. So I got an eight millimeter. Going pretty good. So I'm gonna go ahead and just snug them up a little bit. Gotta make sure that they do tighten up before I stick those bottom ones in. I'm not gonna tighten the whole way, but I wanna make sure that they don't [inaudible 00:07:20] here the bottom. Okay. Now comes the fun part. The bottom ones. You can go ahead and plug this in, too. So I had to get a kit from Dodge, because this would not plug in the whole way. It was too short. So, now I'm just gonna plug it in before I put that in to make it easier on myself, but I forgot... Let's see if I can get it this way. Gonna struggle a little bit, probably. Get it in here to put it on before I put this in there, and then lock it. Okay. [inaudible 00:08:04] Now we're gonna throw one in the bottom here. The wire isn't in there. Good. Another starter, pretty good. Then you go ahead and do this guy. I'm just going snug and then I'll tighten it up like a wheel, four in the corner. And it's just plastic, so you don't wanna go super tight. [inaudible 00:09:35] in the back in here. Okay, I've got everything ready to put this all back in. Okay. I'm gonna reinstall my aftermarket [inaudible 00:09:43]. It came on the car when I bought it. So, like that. Just get it down in here. There's a hole right here with a bolt. That's come with the kit, like I said. I didn't install this, so... Just putting it back the way it was. Oh, yes. I also had to purchase a larger [inaudible 00:10:27], which I'll show you here in a minute. Basically, what this is is it's just this... This side's bigger. That'll fit over this. A little bit easier, hopefully. I know these get a little tighter, so I'm gonna try and get this on first. Use my fingers down inside to push it apart. So that one went pretty good. I'm gonna leave that a little loose, in case I need to manipulate it a little bit. And then I'm gonna stick this guy on in here. Voila. Plug the sensor back in. Hold on a sec. Let me get this in here. [inaudible 00:12:17] Then move the cylinder back in there. She's good to go. Down there and down there. [inaudible 00:13:05]. Oh no. Forgot to put this clamp on. I'm a little excited. It doesn't have to be super tight. Good to hear [inaudible 00:13:58] All right. There we go. I used eight-millimeter sockets the whole time, so it was pretty nice, and then I just had to use the 9/16s to get the can and filter out, so... But we installed the new 90-millimeter B&K throttle body. The new AFE throttle body spacer. There's the part number. And, again, I don't know if it's just my plug for the connection, for the wires, to go into the throttle body. It was a little shorter than anybody else's, but it would not clip. So I had to go get a kit from Dodge, six wire kit, and spliced it all in and got everything going.Jake: That's going to wrap it up for our review and install of the AFE Silver Bullet Throttle Body Spacer for 2008 and newer 5.7, 6.1, and 6.4 liter Hemi Challengers.
