Details:

NGK Laser Iridium High Ignitability spark plugs offer the best combination of performance and longevity. Engineered specifically for OE applications, Laser Iridium High Ignitability spark plugs are tested to the highest standards to ensure quality and durability. Iridium tipped center electrode provides durability six times harder than platinum. NGKs high grade pure alumina ceramic and 98 percent pure copper core prevents the spark plug from overheating while providing reliable starts. Laser Iridium High Ignitability spark plugs feature raised platinum pad or platinum fine wire tip on the ground electrode for even wear in distributorless ignition systems and improved spark performance.

Features and Benefits

• RECOMMENDED USAGE: Best for vehicles with OE DFE iridium alloy plugs

• Trivalent metal plating for superior anti-corrosion and anti-seizing properties

• Pure alumina silicate ceramic insulator provides superior strength and better heat transfer

• Copper core aids in heat removal

• Triple seals prevent leakage
