NGK Laser iridium plugs

were designed specifically for the performance enthusiast. Fine wire center 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
