Note: These sensors are for the first generation Alfano Pro which is no longer made.
You have the option of using up to 1 temperature sensor at a time with the Alfano Pro. You can choose between H20 (water), CHT (cylinder head)
If you have a water cooled motor the most widely used and important temperature sensor would be the H20. This sensor is a 10mm thread. Most TAG motors comes with a fitting in the head. If your motor does not you can purchase a Water Fitting
that you place in your radiator hose lines.
If you have an air cooled motor than you would want to use a CHT sensor. This sensor gets placed under the spark plug. It is 9/16 (14mm) in size.
