NGK Iridium IX Spark Plug

Designed specifically for the performance enthusiast, Iridium IX® offers extreme ignitability, improved throttle response and superior anti corrosion. 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 carbonization, 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 - superior anti-corrosion and anti-seizing properties.
