Key features

• •Dual Holes Automotive Spark Plug Tester: The spark plug tester has two test holes, which can test and compare brand new spark plugs and spark plugs to be tested at the same time. By comparing the spark intensities of the two spark plugs,judge the performance and ignition intensity of the spark plugs,and replace the broken spark plugs in time.
• •0~6000rpm Adjustable Working Frequency: The spark plug tester can truly simulate the working conditions of the engine and can detect the ignition of the spark plug under different working conditions, with a range of up to 0 to 6000rpm/min. You can adjust it according based on your needs by rotating the switch. The higher the set frequency, the stronger the spark intensity.
• •Widely Application: Our car spark plug tester is made of high-quality thermoplastic polymer structural material with good heat resistance and impact resistance to prolong its service life. Widely used for testing 12V gasoline vehicles with a diameter of 12mm. Universal for spark plug tests crankshaft engines and motorcycles.
• •Ignition Timing Light: Design to re-timing your car's ignition to get the best performance that you can. Suitable for car, vehicle motorcycle, marine,all two-stroke and four-stroke gasoline engines, easily operate on 12V ignition systems
