Can Replacing Ignition Coils and Spark Plugs Improve Performance?

[GiannaAnn]

Replacing ignition coils and spark plugs cannot improve performance. Some car modification enthusiasts replace them with better ones to boost power, but this hardly enhances performance. The ignition coil converts 12 volts into tens of thousands of volts, ensuring the spark plug has sufficient ignition energy; otherwise, the spark plug cannot ignite properly. Spark plugs and ignition coils are key components of a car engine's ignition system. Spark plugs are wear parts that require regular replacement, while ignition coils are not classified as wear parts. However, they are prone to damage due to prolonged exposure to high temperatures.
