Spark Plug Gap Size

INFLUENCE OF SPARK PLUG GAP SIZE ON VOLTAGE

The spark plug gap is where the spark discharge is designed to take place.

Too narrow of a gap can yield a spark that is too weak to fully ignite the air/fuel mixture, 

while too wide of a gap can cause misfires during normal driving.

•Applications with low compression ratios and leaner air/fuel mixture tend to recommend a larger gap

•Applications with high compression ratios and dense air/fuel mixture tend to recommend a smaller gap.
