Features: Our spark plug tool set includes features for reducing gaps, increasing gaps, and measuring gaps, making the replacement of spark plugs much easier
Fitment: Suitable for most spark plugs with thread sizes of 10mm, 12mm, 14mm, and 16mm. The red tool accommodates distances from the bottom of the hex to the side electrode ranging from 1.35” to 2”
Adjustment Skill: Due to the metal's memory effect, there will be a slight rebound after adjustment.You can choose a feeler gauge slightly smaller than your desired gap size. Based on experience, a reduction of about 10% is appropriate
Feeler & Gap Gaug: The feeler gauge includes 32 precise blades, with the maximum value of a single feeler gauge being 0.4” (1mm). If your spark plug requires a larger gap, you can combine adjacent sizes to achieve a larger range. For example, you can combine 0.2” and 0.22” feeler gauges to get 0.42”.
Package Includes: 1 x Red Spark Plug Gap Tool, 1 x Feeler Gauge, 1 x Gap Gauge
