NGK LMAR9AI-8D Iridium Spark plug

• High-grade alumina silicate ceramic Creates a stronger insulator to reduce dielectric punchthrough (caused by spark exiting through the side of the ceramic)
• Cold rolled threads Prevents cross-threading and damage to cylinder heads. 98% pure copper core Increased heat dissipation for reliable starts, prevents spark plug overheating
• Trivalent metal plating No anti-seize required
• Ground electrode Designed to reduce quenching effect, resulting in better ignition performance
