It is a vital aspect of engine performance, as it determines how efficiently the fuel burns in the engine.

When the gap is wide, the spark generated by the plug may not be strong enough to ignite the fuel, resulting in misfires. On the other hand, a narrow gap can lead to a shorter spark life and engine damage.
