Description
Better Air Flow for More Power. This Accufab Upper Intake Plenum increases the stock airflow from 460 CFM to an impressive 620 CFM to produce a dyno proven 10 more horsepower and 15 FT/Lbs of torque on a stock factory Mustang, making this Intake Plenum the perfect mod for any 4.6L GT Mustang.

A Must For Larger Throttle Bodies. Installing a larger aftermarket 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 a Accufab intake plenum for improved air flow.

Premium Quality. Accufab's intake plenum is precision CNC machined from high quality cast aluminum and is polished to a brilliant, mirror-quality finish. This Accufab Upper Intake Plenum is built to last.

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

Great!

I bought this Monday and it came Wednesday morning. I installed this plus a 70mm professional throttle body in less than 45 minutes easily, and I can significantly feel the power gain! Go with it!

    It\'s worth it!

    Added this Plenum with a 75mm tb and cai, among other items and could definately tell a huge difference compared to stock. Well worth it and looks sharp under the hood as well.

    THIS PRODUCT IS A MUST FOR THE 4.6 2V

    I JUST RECEIVED AND INSTALLED THE ACCUFAB UPPER INTAKE PLENUM. I HAD ALREADY PUCHASED THE 70 MM THROTTLE BODY. THESE TWO PARTS FIT PERFECTLY AND IT ONLY TOOK A LITTLE OVER AN HOUR TO INSTALL. I DID NOTICE DECENT POWER GAINS AT ALL RPM'S. THE ACCUFAB THROTTLE BODY AND PLENUM ARE A MUST FOR YOUR 4.6 2V. THANK YOU AGAIN AMERICAN MUSCLE FOR GREAT SERVICE.

    Great Plenum

    I purchased this plenum and 75mm TB a few years ago and I haven't looked back yet. Throttle lag disappeared, throttle response increased and the look that it has always get compliments at shows. I would buy it again if I had to, but this thing is solid. This is a one time purchase. It'll be on my car forever.
