    Review & Installation Video

    Hey everyone, I’m Justin with AmericanMuscle.com, 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.

        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 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!

        Hi is this bbk throttle legal in California and will it be an issue when getting the a smog check in California? Thanks for your attention.

        • This would be CARB legal using Carb EO Number D-245-17.

        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.

            Glad I installed it!

            I got one heck of a deal on used throttle body---looked brand new! So I bought it, then after reading some reviews I realized it was probably too big for my 4.6 with bolt on's. So I almost didn't install it. So glad I did install it though, instant smoothness and quicker throttle response, really helped my 4000 to 6000 revs and pull.

            Finally I can breathe!

            To keep it short I installed this and instantly the car runs smoother. I had already cleaned the old throttle body but the idle still seemed to have a mind of its own. Now it runs smoother and who knows maybe we picked up a horse or two...

            Throttle body

            I still need to drive the vehicle . I was trying to install both bbk cold air intake with bbk throttle body. Cold air intake is missing a important gromment to attach both pipes together. Special order. 5-7 days more wait time. Then I will need to officially run the motor.

            Works great! Fits up perfect. Comes with flat gasket. My mustang had the oring style gasket so I just went out and bought a new one, but the flat gasket wouldve probably worked. Deffintly feel more power in higher rpm as well as a deeper intake tone and exhaust note. Might be a bit spendy but defiantly worth the money to give your 2v a little more umph

            Absolutely terrible product

            Everything was going as planned until I tried to put the PCV fitting in to the new throttle body. Absolutely TERRIBLE product. 300$ down the drain, buy a different brand of throttle body. The extremely cheap plastic parts threads do not match the metal threads of the throttle body and it is impossible to get it in. Wasted my time taking apart the old throttle body, waiting for a refund or a new product from BBK, not buying from them again. This is redicolous

            Supercharger Whine?!

            Definite throttle response improvement! The gas peddle feels so sensitive now but I got used to it with a day of driving. The whistling at high throttle sounds pretty cool. I wasn’t expecting that so when I stepped on it I thought there was a Kenne Bell underneath my hood!

            Noticeable throttle response

            Just installed in my ‘04 GT. Very easy and all hardware is included. Works very well with the BBK cold air intake I currently have installed. Drove around for a test drive and immediately felt a quicker throttle response. At higher RPM’s you can hear a slight “whistle” coming in. Sounds kinda cool.
