Warranty Details (60 DAY REPLACEMENT IF DEFECTIVE)
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.

Product Features:
  • ACTUAL OE or EQUIVALENT DESIGN: OEM quality construction fine wire platinum alloy center electrode provides consistent performance
  • PLATINUM ALLOY CENTER ELECTRODE: Longer wearing and higher temperature resistance compared to traditional nickel spark plugs
  • PLATINUM TIP GROUND ELECTRODE: Unless OE specified, platinum protection at the ground electrode provides excellent ignitability and service life
  • SOLID COPPER CORE: 98% pure copper core offers superior heat dissipation, conductivity and ultra wide heat ranges
  • TRIVALENT METAL PLATING: Delivers superior anti-corrosion and anti-seizing properties, ensuring ease of installation and removal
  • RECOMMENDED USAGE: Best for vehicles with OE fine wire platinum alloy plugs
  • Enhanced Fuel Efficiency and Lower Emissions: These spark plugs contribute to improved fuel efficiency and reduced emissions, making them an eco-friendly choice.
  • Superior Anti-Fouling and Stable Idling: The advanced design provides stable idling and superior resistance to fouling, ensuring consistent engine performance.
