NGK Laser Iridium spark plugs (box of four, LMAR9AI-8D) use a fine iridium center electrode and a platinum pad on the ground electrode for extended life and stable spark. Engineered for OE applications, they feature a high-grade alumina ceramic insulator and a copper core for heat dissipation, plus anti-corrosion plating and triple seals to prevent leakage. These plugs aim to provide long service life and consistent ignition performance.
