NGK single iridium plugs were designed specifically for the performance enthusiast. Fine wire centre electrode ensures high durability and a consistently stable spark. Iridium alloy has an extremely high melting point perfect for today's high-tech high-performance engines.

• Trivalent metal plating provides superior anti-corrosion and anti-seizing properties.
• Corrugated ribs prevent flashover.
• Pure alumina silicate ceramic insulator provides superior strength and better heat transfer.
• Copper core aids in heat removal.
• Triple seals prevent leakage.
