Abstract: A combustion pre-chamber device for a spark ignition internal combustion engine is configured to engage a spark plug and be mounted to a cylinder head in communication with a combustion chamber of a cylinder of the engine. The combustion pre-chamber device includes a number of bores that open at an outer surface thereof that extend into the body and receive a coolant flow to provide cooling for a combustion pre-chamber of the combustion pre-chamber device.
