Air Intake Manifold

The air intake manifold is a two-piece (upper and lower intake manifold) aluminum casting. Runner lengths are tuned to optimize engine torque and power output. The manifold provides mounting flanges for the air throttle body assembly, fuel supply manifold and accelerator control bracketry and the exhaust gas recirculation (EGR) valve 9D475. Vacuum taps are provided to support various engine accessories. Pockets for the fuel injectors are machined to prevent both air and fuel leakage. The pockets in which the injectors are mounted are placed to direct the injector fuel spray immediately in front of each engine intake valve.
