The Detector could tell the good spark plugs from the bad by the strength of the spark. Car Spark Plug Tester Using Note: 1. Please Turn Off Power before you place spark plug 2. The Spark Plug Tester is a high-voltage detector, so do not touch spark plug with hand at work to avoid danger. The higher the frequency, the stronger the spark strength.
