Abstract: A sparkplug includes a sparkplug housing, a cathode including at least one electrode prong and being formed predominantly of iridium, and an anode formed at least predominantly of iron or steel. The material compositions of the cathode and anode provide for extended sparkplug service life, especially in high power density applications employing a prechamber sparkplug. Related methodology is also disclosed.
