Get the Perfect Gap with a Spark Plug Gap Tool

Need to check the spark plug gap for your car? Stop the guesswork and get the right tool for the job with our list of 6 different spark plug gap tools. Get your engine running like a dream!

Spark plug gap tools are devices used to measure and adjust the spark plug gaps on an internal combustion engine. These tools help ensure that spark plugs deliver the correct amount of voltage to ignite the air-fuel mixture in the cylinder of an engine, thus providing optimal performance.

Spark plug gap tools typically consist of a flat metal blade with a groove, which fits around the spark plug and allows for accurate measurement of the gap between the center electrode and the side electrode.

Many spark plug gap tools also feature a scale marking on their blades to aid in setting the correct gap size. Adjusting the spark plug gaps may be necessary when replacing or servicing spark plugs and can significantly impact engine performance.

Properly set spark plug gaps ensure that the spark plugs provide enough voltage to ignite an engine's air-fuel mixture and prevent too much voltage from being sent to the spark plugs, which can lead to misfiring. Ensuring that the spark plug gaps are properly set is critical for optimal engine performance.

Spark Plug Gap Tool FAQs:

1. How Do I Use a Spark Plug Gap Tool?

To use a spark plug gap tool, start by ensuring that the ignition system is turned off and that you wear protective gloves. Remove the spark plug wire or coil pack, boot from the spark plug to access and remove the spark plug from the engine, and insert it into one end of the gap tool. 

Then, ensure the electrode on the spark plug aligns with the marks on the gap tool. You can then adjust the distance between the electrodes using a flat-head screwdriver to move the adjustable arm. When you have set your desired gap, remove the spark plug and reinsert it into its socket in the engine. Finally, ensure that all connections are tight before restarting your engine.
