Dual-Hole Spark Plug Tester: A Comprehensive Solution

The Dual-Hole Spark Plug Tester offers a unique advantage – the ability to test two spark plugs simultaneously. By comparing the spark intensity between the two, you can gauge their performance and ignition intensity, allowing you to quickly identify any malfunctioning spark plugs that need to be replaced.

Simulating Real-World Conditions

This engine ignition coil tester boasts a wide testing frequency range, from 0 to 6000 rpm, enabling it to accurately simulate the working conditions of the engine. The higher the frequency, the stronger the spark intensity, providing you with a clearer visual of the spark. This feature makes the tester particularly useful in low-light environments, where the sparks can be observed more distinctly. However, it is not recommended to use this tool in bright surroundings.

Versatile Compatibility and Ease of Use

The automotive ignition tester is designed to be compatible with a wide range of 12V gasoline-powered vehicles, including crankshaft engines and motorcycles. The ease of use is a standout feature – simply insert the spark plugs into the test holes, rotate the frequency knob, and observe the spark plug performance at different frequencies. Even without professional car maintenance skills, you can effectively test spark plugs in the comfort of your own home.

Accommodating Various Spark Plug Sizes

This spark plug tester tool is capable of testing all spark plugs with a diameter of up to 13mm. If the spark plug diameter is 13mm, it will fit the tester's aperture seamlessly. For spark plugs smaller than 13mm, there may be a slight gap between the tester and the aperture, but this does not affect the testing process.

Adaptability for Long and Short Spark Plugs

The tester accommodates both long and short spark plugs: (a) For long spark plugs, simply place shims on the sockets before inserting the spark plug to hold it firmly in place and connect the negative power supply to the socket. (b) For short spark plugs, such as those used in lawn mowers, chainsaws, or small engines, the tester can still be utilized effectively. Even if the spark plug cannot be clamped by the base clamp, as long as it can touch the metal clamp, the positive power supply can be connected. The spark plug can then touch the socket to connect the negative power supply, and the test can be performed, even if the spark plug is slightly tilted. (c) The base clamp supplies the positive power, while the socket provides the negative power connection.
