The NGK Iridium IX Spark Plug (2-BR9EIX / 3981) is a high-performance ignition component designed to provide superior ignitability and durability for demanding engine applications. It features an ultra-fine 0.6mm iridium center electrode that reduces the voltage requirement for spark, promoting stable, consistent ignition even under high-performance conditions. The iridium alloy used in the center electrode offers an extremely high melting point, ensuring long-term wear resistance. This plug is constructed with a trivalent metal plating that provides advanced anti-corrosion and anti-seizing properties, alongside a high-purity alumina silicate ceramic insulator for better heat transfer and structural integrity. A copper core aids in efficient heat dissipation, while triple seals prevent combustion gas leakage. Please verify fitment for your specific application before purchasing.
