Intake Air System

Intake Air System Diagram




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

Intake Air Bypass Control System (Fuel Air (FIA) Control System)




When the engine is running, the Intake Air Bypass control valve sends air to the fuel injectors.

Throttle Body




The throttle body is a single-barrel side draft type. The lower portion of the throttle valve is heated by engine coolant from the cylinder head. The idle adjusting screw, which increases/decreases bypass air, is located on the top of the throttle body.
