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.




Intake Air Bypass Control Thermal Valve
When the engine is cold, the intake air bypass control thermal valve sends air to the injector.
The amount of air is regulated by engine coolant temperature.
Once the engine is hot, the intake air bypass thermal valve closes, stopping air to the injector.




Throttle Body
The throttle body is a single-barrel side draft type. The lower portion of the idle air control (IAC) valve is heated by engine coolant from the cylinder head to prevent icing of the throttle plate.
