Gain Up to 12HP. Gain up to 12 horsepower by replacing your restrictive factory throttle body with a free-flowing BBK 70mm throttle body. Your stock throttle body chokes off the airflow right where it matters most - by letting your Mustang's engine breathe better, you'll increase power and improve throttle response for power you can really feel.

70MM Bore. This BBK throttle body features a generous, free flowing 70mm single bore design that is great for naturally aspirated Mustangs.

CNC Machined Aluminum. BBK's throttle bodies are cast from high quality, lightweight 356 aluminum alloy that is finished using CNC machining to ensure a precision fit. They feature double-sealed bearings, o-ringed throttle shafts, and precision die-stamped linkages to ensure a long life and maximum performance for your Pony.

Bolt-On Installation. The BBK Throttle Body is designed for a straightforward installation and includes all necessary hardware. It is designed to be installed reusing the factory throttle body gasket making it a no-hassle mod.

Application. This BBK 70mm Throttle Body is designed for the 1996 to 2004 Mustang GT with the 4.6L engine.

Technical Notes. This BBK throttle body is CARB certified (CARB EO Number: D-245-13) and 50 state legal.

Can this be mounted to the 78mm body? I bought the 78mm BBK unit from AM and my GT is stumbling at hard accel. Either looking for straight forward answer re: updating my tune/program or just dropping back to the 70mm TB. Suggestions?

Miyagi Year: 2002 Model: GT

  • If your Mustang only has a few bolt-on mods, then it's likely the 78mm Throttle Body is too much. Without a heavily modified engine or FI, there isn't enough air flow to benefit from such a large TB (the 78mm). The 70mm Throttle Body is more than enough for any mild to moderately modded Stang and should help correct the issue you described. Hope this helps! If you have any further questions, don't hesitate to give us a call!

It looks like this throttle body is CARB certified, but only for 96-01 models. Does this mean my 02 GT wouldn't pass smog in California with this installed? If that's the case, are there any 70mm throttle bodies available that would pass smog on my 02 GT?

Is it recomended to also upgrade the upper intake plenum? i've been doing a little research and it seems like you do no need to

bingman Year: 1999 Model: GT

  • Yes, I would change the plenum as well. American Muscle sells a combo kit with a larger plenum and throttle body

    Immediately felt the increase in power. Added with a BBK Cold Air Kit and it not only runs great - it looks great as well. You can hear the air whistle at the Throttle Body and bringing the increased air to the plenum. Easy to install in less than 30 minutes!!

    good gain for the time and money

    A very easy installation on either a stock intake or a CAI. This fits just as well as the stock throttle body and gives a noticeable improvement in throttle respose. This part is a very good early modification for a performance enthusiast. Combine with a tune for even better results. This product exceeded expecations, thanks AM!

    bbk throttle body

    BBK says you get 8-10 extra HP but here's my take. you get that power if you are going for a heavily modified stang. If its force inducted, you will get more power because you are getting more airflow. However, the naturally aspired mustang only takes in so much air and even too big a TB will actually hurt performance. My advice is do your homework and don't follow the crowd. Everyone runs a different setup and the gains if any on a N/A car will be minimal. It would be great if these companies would clarify the "true" power gains of these mods on modified and N/A cars....aside from that AM is the best!!!

    Ok so the rating is not so much for the part itself, as it's a fine product and though it doesn't provide the HP that its said to (which I already knew) the air flow is noticeably louder and seams to give the car a little more breath when wide open, BUT my 3 stars are due to the fact that on my first run in the car when I floored it the thing stayed wide open !!!!, was installed properly by the way as I'm a mechanic by trade.
