• Pure alumina silicate ceramic insulator provides superior strength and better heat transfer
• Trivalent metal plating for superior anti-corrosion and anti-seizing properties
• RECOMMENDED USAGE: Best for vehicles with OE fine wire iridium alloy plugs
• Copper core aids in heat removal
• Triple seals prevent leakage

NGK Laser Iridium spark plugs are engineered as original equipment or equivalent replacements for vehicles that use fine-wire iridium alloy plugs. This set includes four NGK ILTR6E11 spark plugs, part number 90117, designed to deliver dependable ignition performance, reliable starts, and long service life. The iridium-tipped center electrode offers exceptional durability, while the platinum pad on the ground electrode helps promote consistent wear in distributorless ignition systems.
Built to meet demanding OE standards, each plug uses a high-grade pure alumina silicate ceramic insulator for strength, heat transfer, and electrical insulation. A 98% pure copper core helps remove heat from the firing end to support stable operation across a broad range of driving conditions. Trivalent metal plating provides strong resistance to corrosion and seizing, helping simplify future service and replacement.
These NGK Laser Iridium spark plugs are listed for select Buick model years 2005–2010, Cadillac 2005–2014, Chevrolet 2008–2014, Ford 2010–2014, GMC 2007–2014, Mazda 2007–2014, Pontiac 2007–2009, Saab 2011, and Saturn 2007–2010 applications.
