Why are spark plug gaps different?
Why are spark plug gaps different? Spark plug gap is where spark plug spark discharge is designed to take place. On a conventional spark plug, it is the area between the center and the ground electrode. Large spark plug gap setting demands higher voltage (electrical pressure) for spark to jump the large distance gap. What happens if you gap spark plugs to much? If spark plugs are gapped too wide, the ignition spark loses some of its strength as it crosses the spark plug gaps. This can result in engine hesitation. What's the gap on the spark plugs supposed to...
