An ignition system 10 for an internal combustion engine 12 having at least one combustion chamber 22 where the ignition system 10 includes a housing 42, an ignition device 86, an injector 90, and a pre-chamber 50 having a nozzle 92 disposed spaced from the proximal portion of the pre-chamber 50. The igniter portion 88 of the ignition device 86 and the nozzle 92 of the injector 90 are operatively supported in the proximal portion of the pre-chamber 50 and disposed flush therewith. The igniter portion 88 ignites the fuel in pre-chamber 50 such that partially comubusted pre-chamber products are forced through orifices in the pre-chamber nozzle 78 and extinguished, but dispersed through the combustion chamber 22 so as to ignite the main fuel charge therein.
