# NGK Laser Platinum Spark Plug Box of 4 (PLKR7A)

NGK Laser Platinum spark plugs provide high ignitability and longer service life compared to conventional nickel spark plugs. Laser Platinum plugs are tested to the highest standards to ensure quality and durability. Engineered specifically for OE applications. Laser platinum plugs provide stable idling, superior anti-fouling, improved fuel efficiency and lower emissions. High-grade pure alumina ceramic and 98% pure copper core prevents spark plug from overheating and provides reliable starts. Most Laser Platinum 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 platinum alloy plugs
-   Corrugated ribs prevent flashover
-   Copper core aids in heat removal
-   Triple seals prevent leakage
