Features
  • Improves airflow for more power
  • Perfect For Larger Throttle Bodies
  • Durable aluminum construction
  • Fits 1996-2004 4.6L GT Mustangs
Description
Improves Performance. Increase the airflow into your Mustang's two valve 4.6L V8 engine to improve horsepower, torque, and overall performance with a Mustang Upper Intake Plenum.

A Must For Larger Throttle Bodies. Installing a larger throttle body on the stock factory intake plenum still restricts incoming airflow, but now you get the most out of your Mustangs bigger throttle body by installing an upper intake plenum for improved air flow.

Precision Crafted. This Intake Plenum is made from a permanent mold casting of 356 aluminum to produce a higher quality casting than conventional sand molds, which reduces porosity for an improved finish.

Application. The Upper Intake Plenum is a direct bolt-in replacement for all 1996 to 2004 4.6L 2V Mustangs using a Stock, 70mm, or 75mm Throttle Body.

Fitment: 1996 1997 1998 1999 2000 2001 2002 2003 2004 Details

Dave with AmericanMuscle, today I have the upper intake plenum, designed to fit the 96-04 Mustang GTs. The idea in an upper intake plenum is to allow air flow to continue from your airbox, through the View Full Transcript

which throttle body which throttle body would be better? the SR Performance 70mm or 75mm throttle body?

Racin13 Year: 2002 Model: GT

  • If you plan on going forced induction then go 75mm but if not go 70mm. Too much air can cause power loss.

what size is plenum,70mm or larger, What else works well here! I already have a cold air induction system as well.

WILDCAT Year: 1997 Model: GT

  • I believe the plenum will handle throttle bodies up to 75mm.

Question Resolved

Clearance Will the Air Intake tube clear a strut tower brace if the SR Plenum is used with the spacer? (Ford Racing 3 point brace). I now have a minimum amount of clearance as it is with the stock plenum and a BBK CAI. How much extra height does it gain with both pieces? Thanks!

CABorn Year: 1998 Model: GT

  • you can switch out the plenum and still use the brace with no problem but when you add the spacer your adding half an inch in height and that wont allow the spacer to fit I had to remove my brace but its not that bad

    Good balance price/performance

    Bought this and strapped it on, no problems like some of the installation issues I read on reviews of other plenums. Nicer throttle response.

    AWESOME

    All you folks looking thru this site, you won't find a better place for your mustang needs, great prices and even greater service. I put this Stack racing plenum on my mustang with a half inch spacer(also purchased from AM) and you would not believe the difference it made. The torque and hp gain was unbelievable. Thanks AM you've done it again !!!!

    Good for the money!

    Fitment was great except for the rear vacuum nipple which required a larger hose. Rpms seem to hang slightly longer than stock, but only around 1100 rpms then down to normal. This aids in rev matching and overall in town driving with a manual! Worth your while! Thanks AM!

    Who needs Accufab?

    I purchased this with the Edelbrock 70mm throttle body. Installation took about 30 minutes with very few tools. Fit and finish was excellent. Throttle and lower intake faces were flat and true and there are no leaks. The piece is solid and looks better than most I've seen on the market. If you've ever considered the Accufab plenum, but didn't have the cash, you need to consider this plenum for your pony.
