Intake Manifold

WARNING: This page is about a different car, the 2007 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.

The cast aluminum intake manifold incorporates passages for air intake to each cylinder and a passage for the exhaust gas recirculation (EGR) system. The drive-by-wire throttle body and the intake air temperature (IAT) sensor are mounted to the intake manifold. The positive crankcase ventilation (PCV) hose and evaporative emission (EVAP) valve are connected to vacuum fittings on the manifold.
