      • Gain up to 10 HP.
      • Improves Throttle Response
      • Bolt-On Installation

      Gain Up to 10HP. Wake up your 3.8L-powered Pony and launch faster off the line with a Power-Plus BBK Throttle Body. By replacing your restrictive factory throttle body with a free-flowing 56mm BBK part, you'll gain up to 10 horsepower and improve throttle response. Your factory throttle body forces air to bottleneck right where it matters most, and by improving airflow you'll maximize performance.

      56MM Bore. Your factory throttle body keeps your V6 from breathing deeply and giving you all it's got. By bolting on a free-flowing 56mm BBK throttle body, your Mustang will get the air it needs to fuel the fire under the hood.

      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 56mm Throttle Body is designed for 1994 to 1998 Mustangs with the 3.8L V6 engine.

      Technical Note. Stock intake manifold may require port matching for proper fitment.

        Nice product

        Easy to install after measuring the factory one that is supposed to be 60mm but 53.6mm this one has better throttle response. The only issue was the idle screw vibrated down but was easily fixed with a m6 jam nut to hold it in place

        Easy upgrade

        This 56mm throttle body for my 1995 sn95 was an easy installation and with new sensors it has noticeable increase in torque and hp. Looks awesome too!! The only issue I had, as others have had, is that the nuts with shoulders foul the side of the body at two of the four mounting holes. Easily fixed by using my Dremel and grinding a little off of the throttle body housing so the nuts would sit flush.

        it sucks

        when i installed this throttle body on my stang it actually made it slower i could not accelerate at all i gave it full throttle and my car fell on its face my factory throttle body works better then this i even got a few mechanics to see if they knew the problem and a certified ford machanic none of them knew why this throttle body performed the way it did i didnt think id be paying for my car to go slower then it is

        The under bolts

        This is a great product the only complaint I have is my bottom right nut that screwed onto the bolt would not go back on, the throttle body was blocking it, so I had to get another 13mm nut withought the little washer around it so it would fit on. Also as everyone else said the TPS screws do NOT come out very easily. I ordered 2 more screws and just went ahead and threw a new TPS on it.

        Breath baby, breath

        I didn’t see the gain I wanted from my cold air intake, so I decided to replace the throttle body. Man what a difference. She sounds completely different under acceleration. Install was easy and straight forward.

        I was a little skeptical about it but when you take it out of the box and have it side by side with the original it’s like another world completely more sound power and response long wait from back order but totally worth it

      what is the factory size of the 98 3.8l v6 throttle body?

      • Same exact size as this one, actually. 56mm. This one is just a little more free flowing in my opinion. It does help a little, but unless you have a need to flow more air freely, you won't notice much right off the bat. You'd honestly be better off getting rear end gears for pretty much the same price, for a lot more noticeable performance.

      What would be best? I have a 1997 v6 mustang with an intake and I was wondering if I should go with a throttle body or a tuner. What do you suggest?

      • A tuner or the BBK 56mm Throttle Body (94-98 V6) would both be great modifications for your 97 V6!

      How do you put the new bushing on or change the old one out?

      • You can simply remove the old bushing and then install the new one.

      Actually between 94 and 98 the Essex 3.8 mustang has a 60mm throttle body! So why would someone downgrade to a 56mm????

      • If you have a larger throttle body and install this one, you'll likely lose power. So, unless you are trying to lose power, I would advise against purchasing and installing this if you do indeed currently have a larger throttle body in your application.

      If this is the same size as the oem throttle body, how is this an improvement.? What makes this better?

      • This throttle body by BBK would be less restrictive than the factory throttle body which would allow more airflow and allow your Mustangto perform a bit better.
