Has anyone installed a temperature gauge on a 103 twin cam like the Trail Tech units seen here: https://www.trailtech.net/en-us/shop...mm/?pfm=Browse


These use a sensor that sits under the spark plug. Seems like this would be a nice inexpensive means to monitor engine temperature but I am not sure if the is room to get that sensor under the spark plug as the plug sits down in the head a little. Anyone tried one of these?
