With very long lifespan, the Brisk Iridium Performance spark plugs are the most modern design to fit modern highly efficient and stressed engines. 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 prolonged idling.
