Accufab '96-'98 Cobra, 01 Bullitt Mustang Throttle Body Installation Guide

Installing Your Accufab 96-98 Cobra Throttle Body in your SN-95 Cobra

• Preparing for Plenum Removal
  My installation procedure will vary slightly from Accufab's install instructions on their website. Accufab says you can do the installation with the manifold on the car. This can be done to cut time down on the install; however metal shavings will go everywhere when you start to cut with the Dremel. Therefore this install will actually have you removing the upper manifold and plenum from the car.

• Disconnect your throttle position sensor (#5) from the wiring harness. It is only connected by a simple clip that can normally be removed by just using your fingers.
• Remove all of the accessories from the upper intake. These are all held on by either 8mm or 10mm bolts.
• There are only two things that will need to be unbolted from the upper manifold: your IAC Sensor (#3) and your EGR (#2). Both are held on by two bolts and both have a metal gasket in between the accessory and the manifold. Make sure you keep these and set them aside.
• The only other things you will need to disconnect is a rubber tube underneath the plenum elbow and the vacuum line that is on back left side of the plenum which is also a rubber piece. The rubber lines are connected to the two barbs at the bottom of the image.
• Remove the accelerator cable cruise control cable and tension spring from the throttle body.
• You should notice that there is a bracket that holds the cables over the manifold. Unbolt that bracket and move the cables aside.
• After the accessories are disconnected look for the six bolts that hold the upper manifold onto the lower manifold and remove them.
• Remove the upper manifold. Watch out for the composite gasket in between the upper and lower manifolds. You do not want to cut or lose this gasket as it is not cheap to replace. Luckily you can re-use the gasket so you don't have to buy a new one. Let’s hear it for Ford and their engineering team!
• Cover up your exposed intake with a towel or something of the sort and shut your hood. Head on into your garage or shop area.
• Removal of the Stock Throttle Body and Modifying the Plenum

1. Removal of the stock throttle body is quite simple. All you need to do is unbolt the four bolts that hold it into place.

2. There is a gasket that is between the stock throttle body and the upper manifold. Remove that and toss it in the trash. Accufab gives you a new gasket.

3. Now you should see the problem of why the manifold has to be modified. The plenum is setup for the stock throttle body which is a twin bore throttle body. There is an aluminum piece that is in the center of the opening that is about 4-5mm thick. Thesis what we will be removing.

4. Go ahead and get your Dremel out and put on the fiberglass reinforced wheel.

5. Take your intake and lay it flat so that it is not rocking everywhere. You might want to consider stuffing the inside of the intake with a towel or something of the sort to keep aluminum shavings out.
