Spark Plug Feeler Gauges
Keep spark plugs working efficiently. These feeler gauges slide between the electrodes to measure the gap. If the gap is incorrect, they have an adjustment tool to bend the electrode where you need it.
Wire gauges measure using different wire thicknesses. Scale gauges measure along their length—they taper toward the end.
