You will also need to remove the fuel injectors and fuel rail. Please see our article on how to remove your injectors and rail before going further.

Begin by removing the rubber intake from the throttle body as well as the small hose attached to the front of the throttle body assembly.

At the front of the engine remove the two 10mm nuts holding the vacuum lines and the two 5mm Allen bolts holding the self. With the bolts removed lift the shelf up and off the dipstick tube. Slide the shelf out of the way. Remove the 6mm Allen attaching the intake manifold to the alternator bracket.

Next remove the vacuum lines from the top of the intake manifold, and the two from underneath.

Unplug the knock sensor on the engine block below the number 1 and 2 intake runners.

Next, remove the two 10mm nuts and eight 10mm bolts that hold the manifold to the engine. You also need to remove the vacuum line through the number 3 and 4 intake runner.

Lift the intake manifold off the two lower studs and remove it from the engine. Remove the old gasket.

Carefully clean the intake port mounting area, install a new gasket and put everything back together.
