5. Disconnect the following engine wire harness connectors and remove the wire harness clamps from the intake manifold:

- Intake air temperature (IAT) sensor connector (J35A6, '07 model J35A7 engines)
- Throttle actuator connector
- Manifold absolute pressure (MAP) sensor connector
- Evaporative emission (EVAP) canister purge valve connector
- Intake manifold tuning (IMT) actuator connector ('07 model J35A7 engine)

6. Remove the upper cover mounting bolts and nuts sequentially in three steps.






7. Remove the intake manifold mounting bolts and nuts sequentially in three steps.





8. Remove the intake manifold.

NOTE: Do not screw and unscrew the 6 mm bolts securing the upper intake manifold and the lower intake manifold.

Installation

1. Install the intake manifold. Tighten the bolts and nuts sequentially in three steps. Always use a new intake manifold gasket.
