Idle Air Control Valve

The IACV regulates idle speed of the engine, raising and lowering it as needed. The ECU does this by opening and closing a valve to allow more or less airflow into the intake manifold when the throttle is closed.

K-Series engined Elises use a Rover IACV (Part No. MLZ100090)
