Lincoln F8AZ-9424-CB Inlet Manifold Assembly

During installation, ensure the gasket is in place and position new gasket(s) onto the lower intake mounting face. Secure the air intake plenum and throttle body assembly with the six upper intake manifold retaining bolts, tightening them to the specified torque.

The lower intake manifold bolts and nuts should be loosened in 1/4-turn increments until they can be removed by hand.

After completing the installation, you should reassemble the components and check for oil and coolant leaks at the intake manifold joints after starting the engine.

Relieve fuel pressure, remove the air intake plenum assembly on 5.0L engines or the air intake assembly on 4.6L engines, and remove the fuel rail assembly. Detach the electrical connectors from the injectors, remove the injectors, inspect and replace injector O-rings and other components as needed. Lubricate new O-rings with oil before installation and twist to install the injectors. The remainder of the installation is the reverse of removal.

The intake manifold is manufactured of plastic instead of aluminum, and the throttle body is attached to a throttle body spacer that is attached to the center of the intake manifold.
