Remove (4) bolts on the Throttle Body and be careful not to drop gasket.

You don’t get one with the new plenum.

Carefully, remove the Throttle Body (4) bolts using 5mm Allen

Remove the remaining (6) center black 10mm bolts and lift off the plenum.

Here is the inside of the lower plenum. As you can see it is really dirty and the bigger arrow points to some radiator fluid along the back.

Screw in the (4) new bolts that came from Crawford in the 4 holes on the inside of the lower plenum (see arrows).

These are all of the bolts that need to be taken off to get the plenum off. Then they all get put back on with the new plenum with the exception of the (6) in the middle.
