NGK 5044 Iridium IX Spark Plug - BR8EIX, 1 Pack
fine wire center electrodes ensure high durability and consistently stable spark
iridium alloy has an extremely high melting point, perfect for today's high-tech, high-performance engines
pure alumina silicate ceramic insulator provides superior strength and better heat transfer
copper core aids in heat removal
triple seal prevents leakage
Fit type: Vehicle Specific
Designed specifically for the performance enthusiast, Iridium IX offers extreme ignitability, improved throttle response and superior anti-fouling. The 0.6mm laser welded fine iridium tip ensures high durability and a consistently stable spark and the tapered ground electrode minimizes electrical quenching effect. Longer insulator nose prevents fouling, the corrugated ribs on insulator prevents flashover, and a triple gasket seal eliminates combustion gas leakage. Iridium alloy has extremely high melting point, giving it high durability to heat and electrical wear, perfect for today's high-performance engines. Trivalent metal plating has superior anti-corrosion and anti-seizing properties.
