  • Dyno proven 11 HP gains.
  • Better throttle response.
  • Mirror polish finish.
  • Lightweight aluminum construction.
  • Bolt-on installation.
  • Fits 96-04 GT Mustang.

Gain Up to 11HP. Replace your restrictive stock throttle body and gain up to 11 horsepower with Accufab's 70mm throttle body and plenum combo. Your stock throttle body chokes your GT's airflow when it counts most - right at the front of the intake manifold. By replacing it with this Accufab combo, you'll increase off-the-line responsiveness for power you can really feel.

Dyno Proven. Accufab's throttle body and plenum combo have been dyno-proven to deliver gains of up to 11HP and 15 ft-lbs of torque on a stock Mustang. Plus, there were gains of power throughout the entire RPM range, making this must-have mod for any performance enthusiast.

70MM Throttle Body. Great for mildly modded and stock 'Stangs, this generously sized 70mm throttle body opens up the airflow to your engine without overdoing it.

Premium Quality. All of the components of this kit are made from the highest quality, lightest weight materials that are all CNC machined for precision. The throttle body is billet aluminum and the plenum is cast aluminum, both polished to a brilliant, mirror-quality finish. This combo looks almost as great sitting under your hood as it performs on the street or strip.

Bolt-On Installation. Accufab's throttle bodies and plenums are designed for an easy, straight forward installation.

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

Technical Notes. Idle Speed should only be set by adjusting the Throttle Position Sensor. DO NOT adjust any screws on the Throttle Body. These screws are pre-set at Accufab.

Would this work best with a AirRaid CAI? I have the AirRaid CAI and was wondering if the 70mm combo would work best with that CAI or would the 75mm combo work/fit better?

  • Technically, both the 70mm and the 75mm TB and Plenum Combo's will fit with your Airaid CAI. What you need to consider are the other mods done to the car, as well as what you plan on doing in the near future. This 70mm combo is perfect if you have a mild to moderate number of bolt ons. It gives you more air flow without being too much. The 75mm combo is ideally for supercharged applications that need as much air as possible or a heavily modified mustang. If you are planning to do some heavy modding, I'd suggest the 75mm instead. If you are leaning toward mild to moderate upgrades, this 70mm would be your best option!

Is this optimal for my plans Only mods are underdrive pulleys and cai right now. I plan on: full exhaust (long tube headers, H-pipe, ultra flows) gears, tune, drive shaft, coils, and plugs. No plans for a pa (at least for a while).

  • Yes and you won't be disappointed. I have a 2003 GT and I added this to my existing mods (similar to your plans), which are cai, long tube headers, o/r x-pipe, 3.73's, underdrive pulleys and a custom tune. What you can expect is an awesome throttle response, noticeable gains and looks great too!

  • If your Clutch is in good working order you will have no problem with all of your add on's you have maybe added 50-60HP and 40-50Ft/lbs Torque you will be fine. Happy Motoring!

    Great product

    September 10, 2011

    So I installed this on my 04 gt. I have an cold air intake, cat back exhaust and tune. I want to say that I noticed a huge increase with this combo but I only noticed a little change in the noise. I'm sure I did gain a little more power. It's just hard to judge, maybe a dyno could tell more. I will say that the product went together great and looks amazing. I would recommend getting this product. The Idle did go up by about 100 rpm but who cares. I did notice the idle kick-down takes about 5 seconds to kick in. other then that I would buy it again.

    Excellent T/B plenum!!!!

    October 14, 2010

    I just got this throttle body / plenum combo from A/M and it is awesome! I put this on my 03 GT, Instant difference in throttle response and more torq/HP accross the board! A/M shipped it same day and I had it in 3 days! My idle rpm went up to about 900 but a quick SCT tune fixed that right up. This is a must get bolt on! Instalation took about 30 mins! Thanks guys!

    This was definitely a easy way to get a good bit more HP out of your stock GT! This product with a good cold air intake system really helps your GT build RPMs the way it should! Installation was very easy. This was a fun bolt on and you will get reasonable gas mileage when you are in or out of the throttle. Its a must buy!
