Height adjustable

1 Spark Plug Tester. This design not only dramatically improves testing efficiency, but also quickly identifies trouble spots. Battery clamp design. It can simulate a maximum of 9,000rpm of real engine speed (speed range 500-9,000rpm), and through the simple operation of the rotary switch, it can simulate the various working conditions of the spark plug when the engine is running.
