Intake Air System

The system supplies air for all engine needs. It consists of the intake air pipe, Air Cleaner (ACL), intake air duct, Throttle Body (TB), Idle Air Control (IAC) Valve, fast idle thermo valve (A/T model only), and intake manifold.
A resonator in the intake air pipe provides additional silencing as air is drawn into the system.

NOTE: Only VTEC engine has the IAB system seen in illustration.
