Spark Plug Testers

Quickly Determine If One Or More Cylinders Is Not Firing. 


A spark plug tester is a tool used to determine if an electrical current is reaching the spark plug. The electrical current then ignites the air and fuel mixture inside the cylinder to create power. Thoroughly checking the sparkplug itself for damage may prevent the engine from starting. Having a spark plug tester saves you time by allowing you to verify if the problem is the ignition.
