    Review & Installation Video

    Review & Install Video

    Hey, guys, Adam here with americanmuscle.com. Today, I'm bringing you a quick overview of the BBK 73 millimeter throttle body intake, which will be available for all '96 to '04 4.6 liter GT Mustangs. In this video, of course, we'll be going over the performance and benefits you can expect out of the throttle body intake system from BBK, as well as its materials and construction. I'll top the video off with the install, which I'll let you know up front is going to be a one out of three wrenches on our difficulty meter because throttle bodies are, honestly, one of the easiest things you can do to your 4.6 liter Mustang. The BBK 73 millimeter throttle body intake I have here today will be for any '96 to '04 4.6 liter owner who's looking to get a better throttle response overall, as well as a bit more acceleration off the line, while also picking up one of the easiest bolt-on mods you can possibly do to that engine. Before I jump into the juicy details about the 73 millimeter throttle body, I want to point out that, usually, people say bigger is always better. Now in the case of throttle bodies, that is not the case. The 73 millimeter throttle body is going to be one of the bigger options you can add to your 4.6 liter GT, but you don't want to go this big unless you absolutely need to. So what I mean by that is, if you have basic bolt-ons, including a full exhaust, you might be warranting the 73 millimeter throttle body, but if you just have a cold air intake, the 73 millimeter is probably not going to do you too much good, in which case, you might want to look at just a 65. But, with that said, if you've got those full bolt-ons, including a full exhaust, the 73 millimeter can definitely improve the throttle response and acceleration, but not by entirely too much. The good thing about this particular option from BBK is, you get the throttle body and the plenum attaching to your intake manifold. What that basically does is controls a little bit more of the airflow, and with the 73 millimeter housing here, more airflow, you get a little bit more room in the throttle body and the elbow here connected to your manifold, pulling it a bit more than just a typical throttle body. Now, with that said, it is going to cost you a bit more, which I'll touch on in just a second, but this is great for the guys who really need that little bit of extra airflow. And, of course, it's going to go great with a forced induction application, but if you don't have one and you're going to naturally aspirate it, this can do you some justice, as well. For the guys out there who are going to benefit from this 73 millimeter option from BBK, I don't want you to expect a world of difference when it comes to power. Now, as far as horsepower and torque, expect low single-digit gains, of course, but you are going to notice a small difference in throttle response and acceleration, something that the throttle body is known to help with. Now, even though this particular option is an intake and plenum combo, it's not going to require a tune. So what that basically means is this does not require you to fine-tune your computer to read for a 73 millimeter throttle body. However, it is recommended to pick up a computer tune simply because, when you tune your computer to read for the 73 millimeter upgrade, you are going to get a bit more performance out of it. Of course, that goes for almost any aftermarket part, as far as performance goes. Giving it a computer tune will definitely maximize its performance, but again, don't expect the world of difference either way. As far as materials and construction goes here, expect a direct OEM fit replacement. It's all manufactured from a lightweight 356 aluminum alloy, CNC machined for a perfect fit. Of course, this will make for a great OEM replacement if your factory one's defective, or if you're just looking for a small upgrade up to a 73 millimeter. With that said, it's also completed in a charcoal powder coated finish, so it even looks good under the hood, and it has that BBK logo printed right on top of the materials, all embedded into the materials. Definitely looks good under the hood, in my opinion, and I do think, with the 73 millimeter upgrade, you'll get that throttle response and acceleration you're looking for. Now, if you're interested in picking this up for yourself and your 4.6, expect to be spending around $250. Now, some people might think that's a lot of money. My personal opinion, it's a pretty average price tag, especially considering you get the 73 millimeter upgrade attached to the plenum combo to go right into your stock manifold. Now, this one isn't going to be for everybody, but of course, if you're looking to pick up a new throttle body here, maybe to replace that stock defective one, like I just said, this is going to be a pretty good replacement. Shifting gears over to the install portion of the video, like I said in the very beginning, throttle bodies, in general, including the plenum intake, is going to be one of the easiest mods you could possibly do to your 4.6 in addition to its cold air intake. With that said, you're going to need some basic hand tools, like a ratchet and a simple socket set, maybe a flathead screwdriver to help you with the clamps. Overall, you're just transferring a couple of sensors, a couple of clamps over to this particular one, but otherwise, it'll bolt directly up to your stock manifold and your stock airbox. Now, for a regular throttle body, it's typically four bolts holding it onto the manifold, but with the extended plenum, you're looking at about six, I can see here, including the TPS sensor, the idle air control, of course the return spring. All those good accessories that go along with it will detach from your factory option and bolt right up to the 73 millimeter from BBK. Once you have that factory one taken off and the bolts removed, as well as the accessories, simply swap it directly out with this intake and plenum, bolt it back up the same way you took it off, and you're good to go. Overall, about 30 minutes or so on the install, and a one out of three wrenches on our difficulty meter. Just to wrap things up here before we get going, if you're interested in picking up a little bit more throttle response and acceleration, and you're looking to replace that stock throttle body with a little bit of a bigger one, you might want to check out the BBK 73 millimeter intake and plenum kit we have here, which is available at americanmuscle.com.

    I have an 02 mustang gt, so far I have only added a c l intake with and 82mm man. I don't know if the 73mm throttle body is best for my mustang or is the 78mm throttle body better. I keep in mind that Im son going to change my gears to 4.10 Also later install an x pipe with long tube headers. By then I'll be ordering a new tune.

    Juan

    • The BBK 73mm Throttle Body Intake would be ideal for your set up as the 78mm throttle body would be more oriented for heavily modified cars.

    I have a 96 Mustang GT, I am new to the modding community. I had just bought a CAI for my vehicle and wanted to also (down the road) purchase the BBK 73mm throttle body intake...but I heard some people say they installed a spacer to go with it. Do I need to buy a spacer when purchasing this part?

    JoshuaH

    • We do not recommend installing a spacer with the BBK 73mm Throttle Body Intake, as this was designed by BBK to work without one. Adding a spacer will add more plenum volume, but would reduce the velocity of incoming air with this throttle intake.

    okay, i have been wondering what a better idea for throttle body size is. currently, i only have a cat-back exhaust and CAI. I plan on putting a TB on, steeda pulley, gears, tune, headers, and comp cams stage 2 along with 47lb injectors. i don't know when i will be able to do the cams and headers, might be months after putting on throttle body and using it for a daily. is this going to be big enough for what i want to do it and not to big for what i already have done?

    ColeZ

    • The BBK 73mm Throttle Body Intake would be perfect for your application, the 78mm BBK throttle would be too big in my opinion as it is only intended for heavily modified applications or supercharged applications.

    From what I have heard there are two different versions of the 73mm throttle body/plenum. Some have the BBK machined into the plenum on top and some come with a sticker that says BBK with blue around it. Does this come with BBK machined into it or a sticker? Thank you very much.

    Red35th

    • The BBK 73mm Throttle Body Intake will come with the BBK Logo Machined into it.

    hi im tracy look for bbk throttle body intake for my 2004 mustang gt so 73mm or 75mm whats the differences

    tracyc

    • The BBK 73mm Throttle Body Intake and BBK 78mm Throttle Body Intake will be identical with the exception of the internal diameter and size of the throttle plate. The 73mm will work best with street going lightly modified vehicles. The 78mm will work best for track cars, heavily modified cars, or turbo/supercharger applications.

      Put this on my 98 and noticed the idle became choppy. upon acceleration there there is a ringing sound coming from the the throttle body. didn't notice any gain in power. wish i could return it but its too late now. would not recommend.

      Great throttle body for the money. Would recommend replacing the O-ring, intake to throttle body seal while you've got the oem tb off doesn't cost much. Install is simple if you can turn a wrench.

      Noticeable

      Noticible increase, directions say use stock bolts for IAC. DONT! Not unless you take about a 1/4"off them. They will poke through to the inside. Have had installed for about 2 weeks now and loctite on idle set screw came off while I was driving. Ended up back itself out so when I left off the throttle... I kept going still.

      73mm throttle body on 04 Gt

      Looks good, easy installation only took about 10 minutes but I already had my entire intake out of the car due to the plastic under the crossover cracking, but does not work with stock throttle cable, you will need a shorter cable or need to find a way to shorten your existing cable to keep your pedal at normal position.

      Not As Advertised

      Right out is the box, this looks nothing like what was pictured. Most parts that come with it have to be modified to fit correctly. Screws are too long for the EGR valve. Plastic screw fitting is a nightmare to try and screw into the throttle body. Had it back together and did not line up properly with the EGR valve. Returned product and not satisfied.
