# NGK Laser Iridium Spark Plug Box of 4 (TR5AI-13)

NGK Laser Iridium spark plugs offer the best combination of performance and longevity. Engineered specifically for OE applications, Laser Iridium 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. Most Laser Iridium spark plugs feature a platinum pad on the ground electrode for even wear in distributorless ignition systems.

-   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
