德尔福怠速马达 MR479 吉利金刚节气门控制阀

Delphi idle air control valve (OEM MR479) directly replaces Geely SinG King and Delphi second-generation models’ idle air control valve, with wide compatibility, precise control of idle intake, and stable idle speed to prevent stalling. Installed, it resolves cold-start difficulties, fluctuating idle speed, and increased vibration when air conditioning is on. If the idle speedometer fluctuates, and there is jerk after releasing throttle or stalling, this usually indicates aging; replacement restores smooth operation.
