Description

For your engine’s spark plugs to work properly, the gap between the center and side electrodes needs to be calibrated perfectly to ensure optimal engine performance. Having the right gap ensures that the arcing occurs at the proper voltage to ignite the fuel and generates the combustion that makes the engine run. When you need to adjust the gap on a spark plug, it’s time to reach for a spark plug gap tool.
