An internal combustion engine includes an cylinder block defining at least one cylinder, a cylinder head at least partially defining a combustion chamber for each cylinder of the cylinder block, and a spark plug bore formed in the cylinder head for each cylinder, the spark plug bore connecting to the combustion chamber and configured to receive a spark plug. A turbulent jet ignition (TJI) pre-chamber insert is press-fit into the spark plug bore, and defining an internal combustion pre-chamber in fluid communication with the combustion chamber.
