Sandfren Car Spark Plug Tester Tool, Adjustable Vehicle Ignition Coil Tester Detector Gauge with Cable, Automotive Spark Plug Diagnostic Tool, Universal for SUV Sedan Truck

• High Quality Material: The car spark plug tester is made of high-quality alloy and plastic materials. Alloy materials are mainly used for detecting connection parts and core conductive components, with good conductivity and wear resistance, and can maintain stable signal transmission. Plastic material is used for equipment casings, which have good insulation and impact resistance, effectively protecting internal precision components from external collision damage.
• Wide Application: The automotive spark plug tester measures 5.51 inch in length, with a ground wire extending 21.65 inch in length. This versatile tool accurately tests spark plug performance and ignition strength across various internal combustion engine-powered equipment. Whether for everyday vehicles, generators, or small power machinery, it enables quick assessment of spark plug condition, supporting maintenance and troubleshooting across diverse scenarios.
• Easy Installation: When using, first connect the crocodile clip of the tool to the spark plug wire or ground to ensure grounding, then connect the detection end to the spark plug, and observe the spark after starting. If it is a purple blue, two centimeter long straight spark, the spark plug is normal. If the spark is red, bent, or interrupted, it indicates a defect in the ignition coil, and this tool can quickly determine the condition of the ignition system.
• Practical Function: The car spark plug tester can quickly diagnose whether the ignition system is working properly, help users quickly locate the fault points and poor circuits of the ignition system, and provide a guarantee for the safety of the vehicle ignition system. Equipped with an adjustable spacing knob, the jumping distance can be adjusted according to different vehicle models (usually within 0.8-1.5cm), suitable for various ignition system detection needs of different vehicle models.
• Transparent Window: The car spark plug tester is equipped with a transparent observation window, which allows users to intuitively and conveniently understand the ignition ignition status. By observing the spark color and ignition pattern, users can quickly determine the working condition of the ignition system. Paired with a sturdy grounding crocodile clamp with a rubber sleeve, it lays the foundation for stable signal transmission and accurate detection results during the testing process.
