Description

NGK Iridium IX single iridium tip: a 0.6 mm fine-wire center electrode for a consistently stable spark
Iridium alloy center electrode with 6x the density of platinum and an extremely high melting point
Tapered cut ground electrode with a reduced quenching design for ignitability, acceleration and fuel efficiency
Solid copper core, 98% pure copper, for heat dissipation, conductivity and ultra wide heat ranges
Trivalent metal plating that resists corrosion and seizing, so the plug installs and removes easily
