A spark plug sensor enables the Trail Tech TTO Temperature Meter to display engine temperature on an air-cooled bike. The sensor takes the place of the spark plug's crush washer to monitor temperature right at the head. The small digital gauge can be mounted on any flat surface using an included double-stick adhesive strip, or it could be bolted down somewhere using (2) M4 screws (not included).
