Do Ignition Coils Need Regular Replacement?

[VanKingston]

Ignition coils do not require regular replacement; they only need to be replaced when they fail. The ignition system of a car engine mainly consists of the ignition coil and the spark plug. The spark plug is a wear-and-tear component that requires periodic replacement, whereas the ignition coil is not classified as such. However, since the ignition coil operates in a high-temperature environment for extended periods, it can eventually develop faults and fail. As automotive gasoline engines evolve toward higher speeds, higher compression ratios, greater power, lower fuel consumption, and reduced emissions, traditional ignition systems no longer meet the requirements. The core components of the ignition system are the ignition coil and the switching device. By increasing the energy output of the ignition coil, the spark plug can generate sparks with sufficient energy, which is a fundamental requirement for modern engine operation.
