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
RECOMMENDED USAGE: Best for vehicles with OE SPE iridium alloy plugs
IRIDIUM ALLOY CENTER ELECTRODE: Iridium's density (6x that of platinum) and extremely high melting point is perfect for modern high efficiency engines
ACTUAL OE or EQUIVALENT HIGH IGNITABILITY DESIGN: SPE tip & iridium alloy center electrode produce the most advanced OE spark plug technology
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.
