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.
Features:
- 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.
