Where does EGT go on 4 cylinder Lycoming engine?

On a 4-cylinder Lycoming engine, the Exhaust Gas Temperature (EGT) probe is typically installed in the exhaust pipe of each cylinder, usually about 2-4 inches downstream of the exhaust port. This location allows for accurate measurement of the temperature of the gases exiting the combustion chamber. Monitoring EGT helps pilots optimize engine performance and fuel efficiency, as well as prevent potential engine damage due to excessive temperatures.
