This part, known as the engine ignition coil or ignition coil , is a crucial electrical component in the ignition system of JAC GA4 (2018-2022) and GS3 (2018-2023) engines. Its primary function is to increase the low voltage (12 volts) to a very high voltage (up to thousands of volts). This high voltage is essential to generate a powerful spark at the spark plug to ignite the air-fuel mixture inside the cylinder, thus ensuring engine operation.
If the car experiences misfiring or sputtering while driving, difficulty starting, or feels a lack of engine power , with the Check Engine Light possibly coming on, one of the ignition coils may be faulty.
⚠️ Important Notice: Please make sure the part matches your vehicle's chassis number before purchasing the product or after ordering.
