  • More Horsepower
  • Great for Supercharged GT's
  • Crinkle Coat Finish

More Power. BBK Performance has designed and patented the first Throttle Intake. A Throttle Intake incorporates a high flow intake plenum and a larger 78mm BBK throttle body all in one great performing unit. This throttle intake is a direct bolt-on and is good for an additional 12 to 15 horsepower.

Quality Construction. This BBK Mustang throttle body is CNC machined from high quality 356 aluminum to ensure OEM quality and a perfect fit. Features like OEM die stamped throttle linkages, double sealed bearings, and o ringed throttle shafts make this throttle body one of best on the market today.

Application. BBK's 78mm throttle intake is designed to be a perfect fit on all 1996 to 2004 4.6L SOHC GT Mustang. This BBK brand throttle body reuses the stock throttle body gasket.

Please Note. A 78mm throttle body works great on a heavily modified or supercharged GT mustang, because stock or mildly modified GT's do not flow air enough to benefit from the larger Throttle Body.

Technical Note. This BBK product is not legal for use in emission restrictive states.

Hey everyone, I’m Justin with, and today, I’m going to break down the BBK 78 mm throttle intake for all ’96-’04 Mustang GTs. This product from BBK combines two of their most popular items: the tried and true larger diameter BBK throttle body along with a very popular two-valve mod, the larger diameter intake elbow. This has combined it in one very sleek package that is a lot cheaper than ordering both products separately. Why would you want something like this versus your standard normal diameter throttle body? Well, as soon as you place a larger diameter throttle body on your stock intake plenum that is not port matched (meaning it is not matched to 78 mm), you’re instantly losing out on all that extra flow thanks to that larger throttle body. This kit from BBK takes care of all that. This throttle intake is offered in a massive 78 mm diameter, which will allow for maximum airflow. That’s also going to help with your looks under the hood as well, thanks to that very sleek black finish. That large diameter will be perfect for your forced induction setups, including superchargers or turbochargers when you have to move the absolute most amount of air through your motor. Installing this throttle intake for the first time is a relatively painless task that should only take a couple hours. You will need to transfer over both your intake air control valve and your TPS sensor from your stock unit over to the new BBK. After that, simply reinstall in reverse order, plug everything in, and you should be good to go. So if you’re looking to increase the airflow in your 2 valve 4-6, all the while increasing your throttle response and getting some big top-end gains, you’ll definitely want to check out this throttle intake from BBK Performance.

stock will this fit stock parts like the intake manifolds.


  • All the factory sensors and vacuum hoses attach exactly as the stock plenum/throttle body. You can use your stock rubber intake tube but it will take quite a bit of prying and pushing to make it fit over the larger inlet opening of the BBK, and you will need a larger hose clamp.

How much does this weigh? I'm going to have this shipped overseas. I want to know the approximate weight of this product.


Question Resolved

this and a cai? theres a package thing that says you can get this and a cai together for around $450. would a cai be enough for this to see improvements? or would it even be worth it.


  • If the CAI and this TB would be your only mods, then this 78mm TB would be too large to see the full benefit. Mildly modified Stangs don't flow enough air for this large of a throttle body and a 70mm would offer better gains. Bigger does not always equal better in this instance. If you plan to highly modify your stang and wanted to start with this throttle body and cold air combo, it certainly won't harm your engine. Just know won't see the full power gains until you have a large number of bolt-ons or a supercharger. Hope this helps!

    Interesting Gains

    Before you purchase this product you have to note that on a naturally aspirated 2V motor the gains are on the top end... when you hit about 3000 RPM you feel the increase in power, the best logical explanation is this... You are increasing the diameter of the throttle body you so you are decreasing the velocity (speed) of air entering the motor. Off the line it is a little bit sluggish BUT the gains are so noticeable that you feel it pull just like a turbo. The throttlebody also whistles when you shift gears, it sounds awesome. RECOMMEND this product all day, just make sure you don't buy the biggest intake pipe out there so you regain some of that velocity. :) YOU WILL FEEL THE GAINS at 3000rpm, for you speed demons you will be utterly impressed. I give it 5 stars all day. You just have to take into consideration that this is a low velocity TB so you will experience some turbo lag type symptoms. I love mine and the pictures don't do justice for the appearance :) BUY, ENJOY, BE IMPRESSED!

    Great Procuct!!!

    Just had this put on today and all i can say is wow! I also have the BBK cold air intake and it really improved my throttle response. It does have a small whistle but that is normal because of more airflow. Even if you have a stock gt, save your money and get this instead of getting a seperate plenum and throttle body. Don't worry about 70mm or 75mm. This is all you need.

    BBK 78 mm Throttle Body.

    Very pleased with this BBK throttle body. Install time was 2 hours, and the black and silver finish looks so much better over my old stock running pony TB. I notice the power difference when I take off from a greenlight or just an occasional drag to test her. This TB really opens up and you can feel the difference in the way the car sounds and extra emmphh... when she roars. Along with the BBK tuned shorty headers and Pypes midpipe, with violators, My stang now wakes the dead and sounds equally mean as she looks. Thanks BBK and American Muscle. JohnW

    BBK 78 MM

    I have a supercharged mustang gt and this has made a huge difference. I was blown away at the difference in response time and the power it unleashed. The only thing i didnt like about it is that it is so big I had trouble finding a hose connector to fit it so I heated the hose i had and got it around it. I would recommend to anyone with a supercharger. dont know about and N/A motor though
