Description

Keep your Supra idling steadily with the Standard Ignition Idle Air Control Valve (MPN AC426). It fits as a direct-fit replacement for the 1993-1998 Toyota Supra, metering the air that bypasses the closed throttle plate so the engine control module can hold the target idle speed.

Regulates idle airflow: controls the volume of air routed around the closed throttle plate, letting the ECM maintain a stable idle under changing loads.
Signs it may need replacing: rough or unstable idle, stalling at stops, hard starting, or a high or fluctuating idle — if a failed idle air control valve is the cause, this replaces it.
Direct-fit application: a direct-fit replacement for the listed 1993-1998 Toyota Supra.

Because a rough or fluctuating idle can have several causes, diagnose the source before replacing this valve. Interchange: 29908 · AC4027 · 2-19377 · 219377 · 2227046060. Manufacturer part number AC426.
