Airtex 4J1062 Idle Air Control Valve IAC Bypass Valve

The Airtex 4J1062 is a direct-fit Idle Air Control (IAC) Valve, also known as an idle air bypass valve, designed to restore precise control of engine idle speed. The IAC valve regulates the amount of air bypassing the throttle plate at idle, allowing the engine control module (ECM) to maintain a stable, consistent idle under varying load conditions such as air conditioning engagement, power steering input, and electrical accessory demand.
