Universal Spark Plug Gap Tool

A spark plug gap tool is a device used to adjust the gap between the center and ground electrodes on a spark plug. The gap is a critical parameter that affects the ignition and combustion process in an engine, and it needs to be set correctly to ensure optimal performance and fuel efficiency. A must-have tool for anyone who wants to maintain and tune their engine for optimal performance. This tool measures precise gaps, eliminates misfires and error codes due to inaccurate gaps on your spark plugs.


  • Premium Quality
  • Precise gaps every time
  • Fix your car faster
  • Designed & assembled in the USA


NOTE: It is normal for some spark plugs electrode springs back. If they do spring back we suggest using a measurement 2mm less than what you are aiming for. For example, if your gap target is 0.44mm we suggest to using 0.40mm this way when it spring back you will get it to 0.44mm. Please note that this will vary for each spark plug brand, manufacturer, and material.
