Intake Manifold
The intake manifold is a friction welded 3 piece composite design that incorporates brass threaded inserts for mounting the fuel rail, throttle body, and wire harness studs. Each side of the intake manifold is sealed to the cylinder head by 4 non-reusable push-in-place silicone sealing gaskets. The 90 mm (3.54 in) electronically actuated throttle body bolts to the front of the intake manifold. The throttle body is sealed by a 1 piece push-in-place silicone gasket. The fuel rail assembly, with 8 separate fuel injectors, is retained to the intake by 4 bolts. The injectors are seated into their individual manifold bores with O-ring seals to provide sealing. 2 fuel rail stop brackets are retained to the rear of the intake manifold by mounting bolts. The manifold absolute pressure (MAP) sensor is installed and retained to the top front of the intake manifold and sealed by an O-ring seal. The evaporative (EVAP) emission canister purge solenoid valve is mounted to the front of the right cylinder head. There are no coolant passages within the intake manifold.
