Upgraded Automotive Spark Plug & Ignition Coil Tester

Upgraded Adjustable Test Hole

The upgraded spark plug tester features a knob-type copper ring design, allowing you to adjust the socket height to fit spark plugs of various heights. It is compatible with all 12V and 24V gasoline vehicle spark plugs, including German luxury cars like VW, Audi, Mercedes-Benz, BMW, Porsche, and Ferrari, as well as crankshaft engines and motorcycles.

Dual-hole Comparison Test

With two test holes, the tester allows you to simultaneously test and compare a new spark plug with one to be tested. By comparing the spark intensity and color, you can quickly judge the performance and ignition strength of the old spark plug. This helps you identify and replace faulty spark plugs promptly, improving engine performance and saving time.

0 to 6000 RPM Adjustable Working Frequency

The spark plug tester simulates actual engine speeds, detecting the ignition of the spark plug under different working conditions from 0 to 6000 RPM/min. The working frequency can be adjusted according to your requirements, with a higher frequency resulting in stronger spark intensity.

High-volt Indicator and Sound Prompt & Superior ABS Material

During testing, a high-voltage indicator lights up, and the spark tester emits a buzzing sound to help you determine the test frequency. Built with high-quality ABS engineering plastic, the tester is durable and resistant to impact, heat, and low temperatures, ensuring safe and reliable operation.

Protective Cover Design

The tester comes with a protective cover that prevents accidental contact and ensures safe operation. During testing, it is crucial to avoid touching the spark plug as the voltage is high. Always cover the protective cover before testing and turn off the switch before removing the spark plug.

Easy Operation & Plug and Play

Simply insert the spark plug into the test hole, close the protective cover, connect the power supply, and adjust the working frequency using the button to start the test. The protective cover allows you to observe the spark plug test status easily and intuitively.

Notes

Our spark plug tester is not compatible with spark plugs other than automotive types, such as chainsaw or lawn mower spark plugs. Compatible spark plugs can be tested using our tester. If unsure, test it to confirm compatibility.
