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.

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.
