Stage6 cylinder head temperature sensor for 14mm Spark Plugs (B prefix NGK spark plugs).

The Stage6 M14 temperature sensor is a simple and effective way to monitor cylinder head temperature on air-cooled engines. Designed to fit under the spark plug, this sensor provides real-time temperature readings without needing to modify the cylinder or cooling system.

Compatible with Stage6 and Koso digital thermometers and multifunction tachometers that use a white waterproof plug, it's a must-have for performance setups or riders who want to keep an eye on engine temps.

Installation: unscrew the spark plug, remove the original crush washer, slide the sensor ring onto the plug and reinstall. It’s a quick and non-invasive way to track temps and help prevent overheating during aggressive riding or tuning.
