    Hey guys, I’m Justin with AmericanMuscle.com, and today I have two different throttle body options from BBK Performance. I’m taking a look at the 70 and 75mm throttle body for the 4.6L V8 found in all 96-04 Mustang GTs. BBK is one of those companies that lives and dies on Mustangs and late model EFI performance, and it shows with all their quality parts, including these throttle bodies. Now both of these options would be a huge upgrade over the ultra restrictive 56mm factory throttle body. Now depending on your setup either the 70 or 75mm throttle body might work out a little better for you, but that all depends on your mods. The 70mm version will be great for those of you with mild bolt-ons, you know, intakes, header, exhaust, those sorts of things. Now this would be a great complement to those mods, and free up any additional power being held back by an ultra restrictive factory throttle body. The larger 75mm version is geared towards more of a radical setup – big cams, nitrous, high compression or forced induction, that would need maximum airflow. Both of these throttle bodies are CNC’d from high quality aluminum alloy and feature beefed up components that will only add to the longevity and quality of these throttle bodies. Neither of these throttle bodies require a tune but it’s always recommended to make the most out of any additional mods. Installing these new throttle bodies is very straight forward and should only take you about an hour. All you have to do is remove the factory throttle body, transfer the TPS sensor over to the new BBK throttle body, using the included gasket. After that, reinstall the new BBK throttle body and you should be good to go. So if you’re looking for more ways to help your 2 valve 4.6 breath a little easier, and you’ve already taken care of the basics, then you’ll definitely want to check out these throttle bodies from BBK Performance.

    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.

        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?

        • The BBK 70mm Throttle Body (96-04 GT) will have a CARB EO number for 96-01 Gts however for the 2002 and up it will not pass CARB regulations. However we do not carry any throttle bodies that will meet CARB regulations for a 2002 GT.

        Upgrading to a 70mm throttle body If I purchase a 70mm throttle body, do I have to do any tuning after installation? Also , should I upgrade the MAF sensor as well? Thanks Peter

        • You can upgrade to this 70mm throttle body without needing a tune or upgrading the MAF. That said, you would see the best performance gains when combined with a tune. Hope this helps!

        Can this throttle body fit onto any CAI

        Will this perform better than the SR Performance 70mm TB? What are the differences?

        • You can expect the same gains from each 70 mm option, however, the BBK is also CARB legal for 96-01 models where the SR would not be CARB certified.

            Lost bottom end power

            Installed the 70mm throttle body, took 20 minutes or so. Car ran fine but I noticed I lost some low end power but gained more top end power after 3,000 rpms. Took it back off. I wouldn't waste your money on this product.

            This is a must have mod for any 4.6 mustang. It's a huge improvement from the stock throttle body. You'll definitely notice the huge difference especially in the higher RPM.

            Got this 70mm throttle body along with a bbk cold air induction!! Took about an hour to install. Completely amazed with the increase of HP, low end torque and even the sound in the stock exhaust!! Throttle response was also increased!! My Pony can breathe and it shows!!!

            Performance Improvement

            Installation was easy. Timed it and had it done in 20 min. Just don't get so excited that you forget to put the throttle cable back on like I did. It's small and falls out of the way-oops. Performance wise-nice and smooth especially on the top end. Better gas mileage.Why didn't I do this sooner! BBK is good stuff!

            Can definitely notice the difference when i press the pedal. Better response. Overall a pretty good product and i would definitely recommend this upgrade to anyone that is looking for some hp gain without a crazy mod. Only took me bout 30-45 mins to get done im not an all out mechanic.

            great!

            Ordered on the weekend and arrived 5 days later. Took less than an hour and a half with your most basic tools. After installing i could feel the difference. Its not a huge difference but you can tell its a bit more responsive. Smoked an infinity afterwards along with my other american muscle bolt ons. The guy said "good s***" expecting an easy win haha.

            Great product. With standard shifting product came in 4 days. Was easy to install. Already had a bbk cold air airtake installed and after installing the bbk 70mm throttle body you can definetly feel the difference in horsepower. I would recommend this product.

            Good throttle body!

            The throttle body is very easy to install. It got shipped to me and I removed my stock throttle body with now problem. I opened the box and saw my new throttle body and I didn't know there would be a brand new TPS along with the throttle body. I installed in on the new BBK body and then installed the new BBK on my car. It started right up and sounded pretty good. I thought it would make a bigger difference on the power but it's a better difference on power and not a HUGE difference. I have Steeda Underdrive pulleys, High Output Coils, Cold Air Intake, and premium NGK spark plugs. I thought it would make all of those components work more in synch but the power is ok. It does feel like it sucks a lot more air though which should equal more horsepower. I will have to see how it does with my fuel consumption after I return to work and drive it daily for over 40 miles. But overall, I recommend it but if you are looking for extreme power, this might now do it.
