DESCRIPTION AND OPERATION

The intake manifold (9424) :

Is a two-piece (upper and lower intake manifolds) aluminum casting.
Runner lengths are tuned to optimize engine torque and power output.
Provides mounting flanges for the throttle body (9E926) , fuel injection supply manifold (9F792) and accelerator cable bracket (9723) and the EGR valve (EGR valve) (9D475) .
Vacuum taps are provided to support various engine accessories.
Pockets for the fuel injectors (9F593) are machined to prevent both air and fuel leakage. The pockets in which the fuel injectors are mounted are placed to direct the fuel injector fuel spray immediately in front of each engine intake valve (6507) .
