The intake manifold consists of two cast aluminum components. Two short bolts in the lower intake manifold and four long bolts, that pass through both manifolds, mount the intake manifold assembly to the cylinder heads. Additionally two bolts mount the upper intake manifold to the lower intake manifold. The throttle body, Barometric Pressure (BARO) sensor, Evaporative Emissions (EVAP) solenoid and tubes, Positive Crankcase Ventilation (PCV) tubes, fuel rail support bracket, fuel injector wiring harness bracket, intake manifold opening cover, and brake booster hose are mounted to the upper intake manifold. The fuel injector wiring harness, fuel rail assembly, and fuel injectors are mounted to the lower intake manifold.
