Ensure Maximum Performance with the Spark Plug Tester Featuring Two Connections Why You Will Love It ✅ Testing with Two Openings: The spark plug tester features two spark plug connections, allowing you to test two spark plugs (one good and one bad) simultaneously. By comparing the spark intensity of both spark plugs, you can effectively assess performance and ignition intensity. ✅ Protective Cap Safety: The design includes a protective cap that prevents the risk of electric shock during testing, ensuring user safety at all times. ✅ Adjustable Operating Frequency: With the rotary switch, you can adjust the operating frequency from 0 to 6000 RPM. The higher the set frequency, the stronger the spark intensity, allowing for precise control of testing conditions. ✅ Accurate Data: The spark plug tester can simulate engine operation and replicate the actual RPM of the vehicle, providing accurate and realistic data for thorough evaluation. ✅ High-Quality ABS Material: Made from high-quality ABS material, known for its impact resistance and heat resistance. This ensures long-term use and reduces costs associated with frequent tool changes. ✅ Plug and Play: Easy to use and requires only the connection of an adapter to get started. The tester is equipped with a power/high voltage indicator that allows for intuitive observation of the spark plug's condition.
