The inlet manifold is a plastic injection molded assembly made from two shells vibration welded together. The intake manifold is mounted directly to the cylinder head with seven bolts and sealed with four flexible seals.
The main function of the intake manifold is to evenly distribute intake air into the combustion chamber of each cylinder.
A Manifold Absolute Pressure and Temperature (MAPT) sensor is located on the top of the intake manifold and secured a screw. The MAPT sensor is used by the Powertrain Control Module (PCM) to calculate air density and temperature and determine the engine's air mass flow rate.
The electric throttle is attached to the intake manifold with four screws. A gasket seals the joint between the electric throttle and the intake manifold.
