Spark plug for an internal combustion engine having a combustion pre-chamber

A method, comprising:

• installing a spark plug in an inner passage of a combustion pre-chamber assembly, the combustion pre-chamber assembly including a first end defining the inner passage and a second end defining a combustion pre-chamber,
• wherein the spark plug comprises:
• a distal end portion comprising a center cathode electrode and at least one ground electrode radially outward of the center cathode electrode, wherein the at least one ground electrode extends along a longitudinal axis from a proximal portion thereof to a distal end of the spark plug;
• an insulator nose extending around the center cathode electrode, the insulator nose having a distal end that is spaced proximally from a distal end of the center cathode electrode;
• a shell extending around a body of the spark plug, the shell defining an annular volume having a proximal portion around the insulator nose and a distal portion around the center cathode electrode;
• an aperture through the at least one ground electrode that opens into the distal portion of the annular volume;
• and
• at least one bore extending through the shell, wherein the at least one bore extends between an inner end of the at least one bore that opens into the proximal portion of the annular volume at a location that is proximal of the aperture through the at least one ground electrode and the at least one bore includes an outer end that is positioned on and opens on an outer side of the shell.
