Ignition Coil 12570553 12558693 3859078 38590782 392889925 Multi-vehicle compatibility

When your vehicle experiences unstable idle, surge during acceleration, abnormally high fuel consumption, or even an illuminated engine fault light, it is likely caused by aging or damaged ignition coils. The ignition coil normally converts low voltage to high voltage to provide sufficient energy to the spark plugs to ignite the air-fuel mixture, ensuring smooth engine operation. This product fits OEM numbers 12558693, 12570553, 38590782, etc., and is suitable for multiple 4-cylinder models such as Buick Excelle (Yinglang), Chevrolet Cruze, Geely Emgrand, etc. During installation, be sure to disconnect the negative battery terminal and ensure the contact surfaces between the coil and spark plug are clean and oil-free to avoid misfire or short circuits after installation.
