One of the key factors that makes a spark plug work well, or not, is the size of the gap between the electrodes. However, if the spark plug gap is too large, the spark is unlikely to consistently “jump” across the long distance between electrodes, thus leading to a rough-running engine or one that doesn’t run at all.
How long do NGK Laser iridium plugs last?

Can spark plug gaps backfire?
Spark plugs that are gapped incorrectly can cause an engine to miss, or run erratically, especially during idle. The incorrect spark plug gaps can cause uneven firing of individual spark plugs and delay engine combustion; both of which can cause an engine to miss or idle erratically.
