    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 will I need to retune my mustang with this tb ? I hav a vortech supercharger installed currently on it

    DonK

    What kind of hp/tq gains are typical with the bbk 73mm tb? Installed it along with the Airaid cai and Bama tune...WOW!!

    Al

    • Usually when combined with a tune you can see up to 5-10 HP/TQ with the upgraded throttle body.

    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.

      Before you buy this

      The throttle body itself is a beautiful finish and did me well until i did some motor work over the winter, a vacuum leak i found on the car upon first start up where it would stick right at 2,000 rpm. Swapped the throttle body with stock and ended up fixing the issue. Buy an SR or Accufab, served me well until i let it sit for awhile.

      It’s great but

      I installed this throttle body on my car and yea it’s a crazy difference. My car accelerates faster and harder. But what they don’t tell you is you have a hard time adjusting the throttle body cable. Theirs a huge slack in it after you install.

      73mm Throttle body

      The throttle body has a better response the regular one. A little bet more horse power, better acceleration, and sound cooler to. Almost sounds under like a turbo. This is a good product for the car. Keep up the great work.

      Great Throttle Body

      This throttle body was a nice replacement for the stock throttle body. It goes well with the typhoon intake. Bolted right in place and the throttle response feels much better. I haven't gotten to open my mustang up cause I'm still breaking in the motor but so far its been great. Also as others have said it does come with a sticker rather than a machined bbk logo. It still looks really good though.

      BBK 73MM Throttle Body

      Overall im happy with it! I installed this TB at the same time with the Airaid cai and Bama custom tune. Totally different car with this setup!!(i also have BBKCeramic shorties, Bassani catless xpipe and Flowmaster American Thunder cat back)...theres just a couple things i ran across that i had to "fix" to install this TB.. First the plastic fitting could not be installed with the iac valve installed and vice versa. I used a dremel to notch out my iac valve to allow the fitting to fit..2nd was the vac port in the rear was angled up slightly allowing the hose attached to it to interfere wih one of the throttle cables. No big, i was able to bend the outlet downward slightly to get the clearance needed. Took all of 5 seconds with a hammer and the open end of a 6" long wrench. Couple taps with the hammer and it was moved enough to eliminate the interference issue(dont strike to hard!!) 3rd is that the BBK logo on the AM site shows its machined into the TB. It arrived with a sticker/stainless plate in its place..would rather have the machines version as advertised but no bigb not a deal breaker and it still looks really good! And last,but not leastb after my initial test drive(WOW) i popped hood to double check everything and noticed that the idle set screw was loose! Would have never thought to check that had i not read a review here where it happened to someone else! I noticed i could move it by hand and that the loc-tite glob that was there was seperated. All i did was line back up the loc-tite globs and put a lock nut on the other side of the set screw. Problem solved.Overall time to modify and install was under 2hrs. None of these issues are complaints as i realize that when installing aftermarket parts there will usually be some modification to make. Just giving everyone a heads up on what to expect!Overall VERY happy with the BBK 73mm TB!!

      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.
