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.

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.

I'm interested in purchasing this throttle body for my 1998 mustang GT as is right now the car is stock. I was wondering if I should go with the 73 or 78 mm throttle body because I am also going to purchase the bbk cold air intake and wanted to know if that would fit it as well. These will be my first mods so any advice?

BrandonL

  • The 78mm Throttle body is generally for heavily modified cars. I would stick with the 73mm throttle body with your set up, this will work very well for you!

I want to upgrade my throttle body, but I am concerned about the change to my exhaust note. It drones at highway speed due to Flowmaster mufflers (previous owner's doing, not mine) and I don't want it to get any worse. How would this affect the exhaust? I believe the mufflers are Flowmaster 40 series, and I have a stock air box with a K N high-flow filter.

Andrew

Hey I'm very interested in this throttle body I have an after market cold air intake and a flow master exhaust I want better throttle response but is this to big for a n/a car ? I don't want any bog to the car when I'm on the gas without a tuner

  • The BBK 73mm Throttle Body Intake is the perfect size for a N/A Mustang. the Larger 78mm is what we recommend for Boosted Mustangs.

Installed new BBK 73mm throttle body and now have a service engine soon light on. Any suggestions as to why?

WilliamN

  • Hey William, That could be a number of different things and is hard to diagnose with out knowing the specific code that shows. Your best bet would be to connect a tuner or similar device to read the error code that pops up and then adjust the vehicle from there.

    BBK 73mm Throttle Body 2001 Mustang GT

    Works great with my 01 Mustang GT. One important note to 01 Mustang Gt owners. DO NOT use the factory bolts for the installation of the idle air control valve back on to the throttle body as the instructions say. If you do you will need a spacer or thick washers. This is a problem for both the BBK throttle body and the SR Performance. Bolts are too long and go through the plenum. It would be good for American Muscle to address this with the manufacturers and get this annotated in the installation instructions.

    BBK 73MM Throttle Body

    The BBK Throttle body was very simple to install. Follow the instructions included and this will be a satisfying and easy install. Make sure to use the bolts supplied for the throttle cable assembly and egr valve. The stock bolts are too long and will penetrate your brand-new throttle body. There was a black plastic spacer that is intended to be used on the throttle position sensor. It would not fit and BBK told me it was for an older model throttle body and that I did not need it. If you have a rough idle, double check that the throttle adjustment screw is where it needs to be, adjust it by simply screwing it in or out slightly. Also, check your vacuum lines and since you are only using 4 of the 5 bolt holes on the manifold with this throttle body, make sure the unused bolt hole hasn't been penetrated all the way through. I had used the PI Intake Manifold on Non-PI heads and the bolt I used from my Non-PI manifold penetrated into the PI manifold and was causing a seriously rough idle. I fixed it by replacing the screw into the hole along with some rtv on top. My 96 GT idles at about 900 stock. Also, I needed a volt/ohm meter to adjust my throttle position sensor. It needs to be between .80-.95 on my car. Very simple to do that as well. I had open headers before and after this install and the growl it added was very noticeable with the open headers. Since then I have added the BBK X mid pipe and the growl remains. It also increased throttle response.

    Don't waste your time

    Very disappointed it got shipped to the wrong house so didnt even know where it was for 2 days luckily person found my address and dropped it off to me then its very difficult to get everything back in place and lined up right once I finally did found out there's no way the bushing will fit into the tps hole on the intake and now getting the run around with am and bbk about getting another one sent to me to fit it. So basically I have to miss work now since I can't put it all back together properly yet untill bbk and am figure out what their gonna do. But if it helps the intake looks nice but not worth the hassle. Somebody needs to get their stuff straight. American muscle has lost me as a customer!!

    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.

    Product is as advertised except it doesn't have the machined/cast BBK letters. Instead it has a cheap sticker. Almost like these are mass produced for any brand to put their sticker on it. Had I known I would have gone another way. It hasn't peeled off yet, but just knowing it makes me angry considering this is not what I paid for.
