About these plugs

NGK Laser Iridium High Ignitability spark plugs offer the best combination of performance and longevity. Engineered specifically for OE applications, they are tested to the highest standards to ensure quality and durability. The iridium-tipped center electrode is six times harder than platinum. NGK's high-grade pure alumina ceramic and 98% pure copper core prevent the plug from overheating while providing reliable starts. Laser Iridium High Ignitability plugs feature a raised platinum pad or platinum fine-wire tip on the ground electrode for even wear in distributorless ignition systems and improved spark performance.

  • Solid copper core: 98% pure copper core offers superior heat dissipation, conductivity and ultra-wide heat ranges.
  • Recommended usage: best for vehicles with OE PSPE iridium alloy plugs.
  • Actual OE or equivalent high ignitability design: PSPE tip and iridium alloy center electrode produce the most advanced OE spark plug technology.
  • PSPE design: the projected square platinum electrode shape of the ground electrode provides the best ignitability and service life for high-heat engines.
  • Iridium alloy center electrode: iridium's density (6x that of platinum) and extremely high melting point are perfect for modern high-efficiency engines.
  • Trivalent metal plating: superior anti-corrosion and anti-seizing properties for easy installation and removal.

The plugs come pre-gapped at 0.7 mm (0.028 in). Check the gap your engine calls for before installing.

Our responsibility is limited to replacing or refunding the part. To the extent the law allows, we don't cover labor, installation or removal, diagnosis, towing, rental vehicles, or incidental or consequential damages.
