Do Ignition Coils Need Regular Replacement?

[HannahLee]

Ignition coils do not require regular replacement; they only need to be replaced when they fail. Here is more information about the automotive ignition system: 1. Composition: The ignition system of a car engine mainly consists of the ignition coil and spark plugs. Spark plugs are wear-and-tear components that require regular replacement, while ignition coils are not considered wear-and-tear parts. However, since ignition coils operate in high-temperature environments for extended periods, they can also develop faults over time, meaning they can fail. 2. Core Components: The core components of the ignition system are the ignition coil and the switching device. Increasing the energy of the ignition coil allows the spark plug to generate sparks with sufficient energy, which is a fundamental requirement for the ignition system to adapt to the operation of modern engines.
