Intake Air System

Intake Air System




This system supplies air for engine needs. A resonator in the intake air duct provides additional silencing as air is drawn into the system.

Refer to the System Diagram to see the functional layout of the system.

Throttle Body




The throttle body is a single-barrel down draft type. The lower portion of the throttle valve is heated by engine coolant from the cylinder head.
