Spark Plug and Ignition Coil Tester for 12V Gasoline Vehicles

About this item

• Wide Range of Compatibility -- This tester is used to test spark plugs (12 mm diameter) for 12V gasoline vehicles, motorcycles, lawn mowers, garden tractors, scooters, snow blowers, boats and so on. A lot of times, spark plugs are the main cause of failure to start. This tester will confirm if this is the case and there will be no confusion. And to verify that the old spark plugs are still working before installing the new ones.
• ABS Transparent Safety Cover Design -- In the spark plug area there is a protective cover on it so that accidents do not occur. Transparent protective cover also allows visualization of test results. Variable RPM to know exactly where your plugs are failing. Made of ABS material for durability and heat resistance. Do not open the cover until the test is complete.
• Quickly Find the Faulty Spark Plug -- In the automobile ignition system, the high-voltage ignition coil generates high-voltage and the spark plug diverts it form high-tension ignition coil into the cylinder engine, spark between the spark plug electrodes will ignite the mixture. The spark plug tester can distinguish a good or bad spark plug by the strength of the spark. The automotive spark plug tester can simultaneously perform dual-hole testing and simulate engine work.
• Automobile spark plug tester allows for testing two holes at once, saving time and increasing efficiency. Easy to use, simply plug in and play. To set a starting point, place a new spark plug on stud 1 and a test plug on stud 2 for visual comparison of spark quality.
• 0~6000 RPM Adjustable Working Frequency -- Allows to set the working frequency in the range of 0~6000 RPM. The spark plug tester can also simulate the engine work and restore the car start, so as to better test the spark plug. You can test one spark plug alone and observe the strength of the spark by adjusting the frequency, or you can test both plugs at the same time and tell the performance of the old spark plugs by comparing the old and the new ones.
