Detailed Description

Standard Ignition AC511 is an idle air control valve used to regulate bypass air at the throttle body so the engine can maintain a stable idle under changing load conditions. It is specified for 2002-2005 Hyundai XG350 and 2001 Hyundai XG300 applications, making it a focused replacement for drivers searching for a Hyundai XG350 idle air control valve or a Hyundai XG300 idle air control valve. The connector and terminal layout are important for proper electrical fitment, and the AC511 configuration uses a female connector with male blade terminals to match the original vehicle connection.

What It Helps Address

• Unstable or fluctuating idle speed
• Engine stalling when coming to a stop
• Idle speed that is too high or too low
• Idle control response problems after throttle changes
• Check engine concerns related to idle air control operation

Installation Notes and Tips

Verify connector style, terminal type, and vehicle application before installation. Clean the throttle body and surrounding air passages during service so the replacement valve can operate against a clear airflow path. Confirm that the electrical connector seats fully and that the idle system is free of vacuum leaks or carbon buildup that could affect idle quality.
