The Iridium core center electrode is surrounded by Yttrium alloy made body and earth electrode that gives very low voltage requirement prolonging ignition coil lifespan.   Lower voltage requirement stands for easier cold starts, less of a chance of a misfire due to fouling as a result of oil burning, use of alternative fuels or prolon
