How often should the ignition coil be replaced?

[McLorenzo]

The ignition coil should be replaced every 100,000 kilometers. The ignition coil is a key component in the automobile engine ignition system. Its main function is to convert the low-voltage electricity of the car into high-voltage electricity, and it can also be called a high-voltage pack. The 12V electricity in the car is boosted by the ignition coil to high voltage to achieve the ignition of the car. When the engine is running, the ignition coil also drives the spark plug to ignite in the form of a fixed frequency pulse. The simplest way to determine if the ignition coil is aging is to open the engine compartment and directly observe whether the ignition coil has symptoms such as glue overflow, cracking, connecting pipe, or high-voltage nozzle ablation.
