Spark Plug Tester Ignition Coil Tester Double Holes Spark Plug Gap Tool (12MM Diameter) 0 to 6000 RPM Adjustable Working Frequency Ignition Test Tools for 12V Gasoline Vehicles
Dual Hole Spark Plug Tester: The tester can test two spark plugs at the same time, allowing you to compare the ignition intensity and the performance of the two spark plugs at the same time. Thus, it lets you know when you need to replace the broken spark plugs for better engine performance. It saves time and keeps your car running more smoothly
Works with Multiple Types of Vehicles: The spark plug tester has good heat resistance and hardness, and can be used to test 12V gasoline vehicles car spark plugs with 12mm diameter, 100V-240V input voltage.
Widely Compatible with Spark Plugs: The diameter of spark plug tester socket is 13MM. If the diameter is smaller than 13MM or the spark plug is too long, we recommend using our equipped washers placed on the socket. Smaller spark plug diameter will not affect the test.
Wide Range of Speed Setting: the test working frequency can be adjusted in the range of 0~6000rpm. Adjustment by rotary switch is convenient. The higher the frequency, the stronger the spark intensity.
Easy to Use and More Clearly: The spark plug tester is easy to operate, after connecting the adapter, place the spark plug into the hole of the socket to start using. The spark plug tester has one power indicator and two high voltage indicators. It lets you observe the performance of the spark plug more clearly by simulating the engine work.
With Washer: For long spark plugs, placing washers in the socket will increase stability. For short spark plugs, even if it can't be fully clamped, touching the metal clip is enough and will not affect the test. NOTE: The clamp on the base supplies positive power and socket supplies negative power.
