    Review & Installation Video

    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.

    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.

    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 ...

    would it be good to use on my almost stock 1999 gt ? All i have done to my car is a K&N intake, flowmaster 40'S mufflers and a BBK catted x pype. im planing on buying a bama tuner so wopuld that help too ?


    • This would be too much air flow for your Mustang's engine. A better choice for power would be a 70mm Accufab or BBK unit. You would see the most gains from these throttle bodies with your combination. I would, also, suggest getting the matching upper plenum. Hope this answers your question and thanks for choosing American Muscle!

    78mm for N/A or smaller?? For a naturally aspirated engine would you get more horsepower out of a larger intake such as this 78mm Throttle intake made by BBK, or would you get more horsepower out of a higher velocity intake with a smaller diameter such as the Accufab 70mm throttle body and plenum?


    • This not so much an answer but a question are you going to remain stock? Upgrading to a larger throttle body is usually one of the first steps besides the exhaust in modding engines so if you are going to remain stock then the 70 mm would get you better gains but if you are going to put cams or power adders then the 78 is a must.

    I have a 03 mustang GT with BBK longtube headers non cAtted bbk mid pipe and slp loudmouth exhaust I do have a S b intake iwanted to buy the 78mm bbk throttle body and get my car dyno tuned right after will this product affect my car in any way?


    • The BBK 78mm Throttle Intake will increase performance and air flow, however since it is after the Mass Airflow sensor and Intake air temp sensors, the PCM is able to read and accommodate for these changes. This part will have little to no effect on the tune because of this.

    would this throttle body fit on a JLT cold air intake?


    • The BBK 78mm Throttle Intake will work perfect with a JLT CAI.

    Do I use the same two screws on the cruise control mount on top


    • The cruise control component will simply pop on and off of this throttle body.

    I had just installed this throttle body today. After finishing and starting the car, it idled rough in a way that resembles a car that is "cammed out". Even though I like the sound it makes, as it is far more aggressive, I want to know if that is supposed to be the reaction. I have an SR CAI already with the throttle body and a custom BAMA tune on its way. I did notice an increase in power and a nice whistle when I shift almost resembling a turbo but not quite. Anyways, please let me know if the rough and aggressive idle is anything to worry about, or if it will adjust over time or with the tune. Thanks!


    • I am sorry to here about this. This may be your TPS. If your Throttle position sensor is off this could be the cause of the hard idle. Give us a call in and we can help you out with this!

      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!

      Exellent product

      Really noticable horsepower gain,better throttle response and it looks great sitting on top of my 4.6.Although I do suggest buying a new tps sensor cost is about 20 bucks. ford used locktight on the screws that hold the tps to the throttlebody,and that can make removing the tps very difficult.

      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

      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

      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

      I bought this a few weeks ago and had it port and polished and it is amazing! It went with my BBK CAI great and I went a head and got a new throttlebody at the same time. It made my the whole car louder! My O/R Hpipe with dynomax mufflers sounds 100 times better. i dynoed 27rwhp with the BBK port and polished and throttle body add on! Great bang for the buck! Thanks AM has always!

      Love it!

      It was easy to install altough i did have to buy a new tps sensor. You can realy feel the air suck in after 2500-3000 rpms. Also it goes real good with da bbk cai. Personaly i believe this is the best t/body to go with and theres no need to buy the upper plenum n t/body when you can have 1 complete piece.

      beware 96-98 mustangs

      Too much volume of air for the 96-98 mustangs. Through my experience the velocity is more important than volume. Causes bogging and low end loss of power and torque. Save your money and get other bolt ons like pi heads etc.

      once i installed and turned on the throttle body my car sounded like a beast. BUT, instructions say to let the computer calibrate to the T/B and once that happened i got a rough idle, left and right bank o2 sensor code, and a cylinder misfire code. i recommend going with sct tuner. once i installed the tune everything went away and the car has been running like a champ ever since.

      Super Sucker

      I bought this Throttle intake without reading any questions from others on this site. Such as is it too much or overkill for my NA stang? I'm hear to tell you NO it is NOT. It is awesome!! Bought this and a SR CAI and can definitely feel the throttle response. From 2,000 rpm and up (wide open) she goes. I have a 02 GT Vert Auto, I click down to 1st (traction off) stomp it click up to 2nd (chirp) and 2nd pulls harder for sure, I just mean when it's wide open and higher rpm you feel this thing working. It's got a cool whistle sound here and there on the throttle, an a slurp when you tap the gas at idle. I plan on doing Forced induction if and when my wallet allows so I feel like this was a good buy for now even though I don't have a lot of mods yet. If your going to spend $ on a Throttle intake this is the one to get. Oh BTW the stock EGR valve bolts are too long, I went to auto zone and bought 1 inch bolts. Other than that great product very happy with it. Thanks AM!
