OBDResource ST100 Automotive Spark Plug Tester – Dual Hole Ignition Diagnostic Tool

The OBDResource ST100 Spark Plug Tester is a professional-grade ignition diagnostic tool designed for fast and accurate spark plug performance testing. Whether you are a professional technician or a DIY enthusiast, the ST100 helps you detect weak sparks, engine misfires, and faulty plugs without needing to run the vehicle’s engine.

🚀 Key Selling Points & Features

1. Efficient Dual-Hole Testing (Simultaneous Comparison)

Unlike standard single-hole testers, the ST100 features Dual-Hole Testing capability. This allows you to test two spark plugs simultaneously, making it easy to compare a new plug against a suspect one to identify performance gaps instantly.

2. Realistic Spark Simulation

Equipped with a high-energy output, this tool generates a strong spark simulation that replicates real engine ignition conditions. It provides reliable diagnostics for gasoline engine spark plugs, ensuring your vehicle runs smoothly.

3. Global Wide Voltage Compatibility (100–240V)

Designed for international use, the OBDResource ST100 supports a wide input voltage range of 100V to 240V AC. This makes it a perfect addition to workshops and repair shops worldwide.

4. Instant Visual Feedback with Indicator Lights

Safety and clarity are prioritized. The built-in Power and Spark Indicator Lights provide immediate visual confirmation of the tool’s status and the spark’s intensity, ensuring a safe and efficient testing process.

5. Simple "Plug & Play" Operation

No complex setup is required. Simply insert the spark plugs, switch on the device, and observe the results. It’s a time-saving solution for pre-installation inspections and post-cleaning verifications.
