Air Intake System

Air intake system on 3.0L engine incorporates throttle body and intake manifold in 1-piece unit. All other engines use 2-piece (upper and lower) intake manifolds. Runner lengths are tuned for optimum engine torque output. Manifold provides mounting flanges for throttle body assembly, fuel supply manifold, accelerator controls, EGR valve and supply tube.

Vacuum taps are provided to support various engine accessories. Pockets for fuel injectors are machined to prevent both air and fuel leakage. Pockets in which injectors are mounted are placed so injectors spray fuel directly in front of each intake valve.
