Air Intake System

AIR INTAKE SYSTEM
System Components
The main components of the air intake system are the Air Cleaner (ACL), Mass Air Flow (MAF) sensor, air intake pipe, throttle body, fast idle air valve, Idle Air Control (IAC) valve and intake manifold.

Air Distribution
The air (by the amount corresponding to the throttle valve opening and engine speed) is filtered by the ACL, passes through the throttle body, is distributed by the intake manifold and finally drawn into each combustion chamber.

IAC Operation
When the engine is idling or cold and the IAC valve is opened according to the signal from the ECM, the air bypasses the throttle valve through the bypass passage and is finally drawn into the intake manifold.
