Automotive Spark Plug & Ignition Tester Kit

Precise Control with Digital Screen Display

The spark plug tester features a digital screen for real-time performance and strength testing. Its up and down buttons allow precise adjustment of the working frequency, ensuring accurate and reliable results. The high-definition display makes it easy to monitor the speed and test outcomes, enhancing overall accuracy.

Simultaneous Testing of Five Holes

Unlike typical two-hole testers, this ignition spark tester supports simultaneous testing of five holes. Each test hole comes with its own indicator light, clearly showing the status of each spark plug. This feature significantly improves work efficiency by saving time and reducing operational steps.

Accurate rpm Simulation for Spark Plugs

The automotive spark plug tester offers an analog speed range of 0-9999 rpm with a maximum operating frequency of 9000 rpm. The higher the frequency, the stronger the spark plug intensity. This tool is compatible with various crankshaft engines and motorcycles, making it a versatile and indispensable choice for professionals and enthusiasts alike.

Simple and User-Friendly Operation

Operating this spark plug tester is as simple as plugging and playing. Insert the new spark plug into one hole and the old one into the other. Connect the power adapter to the power port, and the indicator light will turn on. With the car spark plug tester powered on, you can easily adjust the working frequency to quickly assess the condition of your spark plugs.
