Do I need to change the ignition wires after upgrading the ignition system?

[LeKing]

After upgrading the ignition system, it is necessary to change the ignition wires; otherwise, it may easily cause poor performance of the spark plugs. The importance of ignition wires: Ignition wires are an essential part of the ignition system. Their main function is to conduct high-voltage electricity from the ignition coil to the spark plugs, ensuring their proper operation. Additionally, ignition wires are used to control the firing order of the engine, managing the ignition of the spark plugs and thus regulating the operation of each cylinder. Consequences of not changing the ignition wires: Upgrading the ignition system means the spark plugs require higher ignition energy. The old ignition wires may not match the new spark plugs, leading to potential issues such as electrical leakage, increased internal resistance, and degraded conductivity under long-term high-load operation. These issues will prevent the upgraded ignition system from performing as intended and may even result in reduced power output.
