Product Description

NGK Laser Iridium High Ignitability Spark Plug

Features & Benefits

  • NGK Laser Iridium High Ignitability spark plugs are designed with the most advanced OE tip configurations to maximize service life and combustion efficiency resulting in a quicker throttle response, smoother idle and better cold starts.
  • ACTUAL OE or EQUIVALENT HIGH IGNITABILITY DESIGN: SPE tip and iridium alloy center electrode produce the most advanced OE spark plug technology
  • Laser Iridium plugs are tested to the highest standards to ensure quality and durability. Engineered specifically for OE applications.
  • IRIDIUM ALLOY CENTER ELECTRODE: Iridium's density (6x that of platinum) and extremely high melting point is perfect for modern high efficiency engines
  • Iridium tipped center electrode provides durability six times harder than platinum. NGK's high-grade pure alumina ceramic and 98% pure copper core prevents the spark plug from overheating while providing reliable starts.
  • SPE DESIGN: Square platinum electrode shape of the ground electrode provides the best ignitability and service life for high heat engines
  • 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 SPE iridium alloy plugs
