Professional Spark Plug Tester for Cars and Motorcycles

At-A-Glance Overview

Innovative Dual-Hole Design

OBDMONSTER Spark Plug Tester features a creative and ingenious dual-hole design, differing from traditional single-hole testers. This innovative setup enables you to test multiple sets of spark plugs simultaneously, saving both time and effort. With this tool, your work becomes more efficient and convenient.

Adjustable Frequency from 0 to 6000 RPM

Equipped with a built-in high-precision sensor, this tester can realistically simulate an engine’s working conditions. The frequency can effortlessly be adjusted from 0 to 6000 RPM by simply turning the switch. As the frequency increases, the spark strength also increases. Whether you’re testing new spark plugs or assessing the lifespan of old ones, this tool provides reliable support, helping you make well-informed decisions.

Superior Quality and Durability

Made from high-quality thermoplastic polymer, the tester offers excellent heat and shock resistance. This ensures stable operation, even in high-temperature and high-humidity environments. The device includes built-in overload and short-circuit protection, enhancing your peace of mind and extending the product’s lifespan. It is versatile, suitable for use in all 12V petrol cars with 12mm spark plug diameter, crankshaft engines, and motorcycles.

Portable and Compact

Designed for ease of use and portability, OBDMONSTER Spark Plug Tester weighs only 300g, making it lightweight and easy to carry. Whether for routine maintenance or emergency testing, you can use it anytime, anywhere. Its simple operation allows you to quickly and efficiently test your spark plugs. Just insert the spark plugs into the dual-hole test groove, connect the power, and start testing. It is a must-have tool for every car enthusiast and professional technician.

User Precautions

For optimal results, it is recommended to test in a relatively dim light environment to clearly observe the flame intensity. This tester can handle spark plugs with a diameter up to 12mm. If testing smaller spark plugs, a shim can be placed in the test slot beforehand. The tester is not recommended for testing short spark plugs on most small engines such as chainsaws and lawnmowers.
