How Long Does The Engine Ignition Coil Need To Be Replaced?

The engine ignition coil manufacturer did not clearly state how long it would take to replace it, nor how many kilometers would need to be replaced, but in my actual maintenance process, I found that the ignition coil was damaged in different models or the number of kilometers.

The ignition coil of the automobile engine is also called the high-voltage package, the function is to convert the low voltage into high voltage, the spark plug ignition requires a higher voltage, so the ignition coil is needed to convert the low voltage into a high voltage, thereby driving the spark plug for strong ignition.
The ignition coil of the general vehicle engine can be used for more than 100,000 kilometers, and the general engine ignition coil will cause the engine to shake after damage, and even the engine is difficult to start.

The ignition coil is used for more than 100,000 kilometers, if there is a cylinder of the ignition coil is damaged, it is generally recommended to replace it together, encountered more vehicles, after breaking one of the ignition coils, only replace one ignition coil, and then go back to use the car for less than a month, the engine failure light is on. The inspection revealed that the ignition coils of the other cylinders were damaged again. The back is still all the ignition coils replaced.

Therefore, vehicles with a higher number of kilometers, when one of the ignition coils has problems, the other ignition coils will not take long, basically the life difference is not much, if it is a small number of kilometers, you can not replace it together, you can replace the faulty ignition coil and observe with the car.

After the engine ignition coil is damaged, it must be dealt with in time, otherwise it will have irreversible damage to the three-way catalytic converter.
