What impact does a spark plug gap that is too large have?

A spark plug gap that is too large can indeed strain the ignition coil because the ignition coil has to work harder to generate enough voltage to bridge the increased distance between the spark plug electrodes. When the gap is larger than the manufacturer’s specifications, the voltage required to create the spark also increases. This additional demand can lead to overheating, reduced efficiency, and potential damage to the ignition coil over time. Therefore, maintaining the correct spark plug gap is essential for optimal engine performance, as it ensures a strong and consistent spark for combustion while preventing unnecessary stress on the ignition components.
