The NGK Spark Plugs LMAR9AI-8D Laser Iridium Spark Plug is designed to provide dependable ignition, efficient combustion, and long-lasting performance in compatible engines. This spark plug uses a fine-wire laser iridium center electrode and a ground electrode engineered for consistent spark delivery, helping support smooth starting, stable idling, and reliable operation across a range of driving conditions.
Built for precision fitment, the LMAR9AI-8D model is suitable for applications specified by the vehicle or equipment manufacturer. Verify the engine application, thread specification, heat range, and original-equipment requirements before installation to ensure proper compatibility. The NGK Spark Plugs brand and manufacturer part number 90526 identify this component for accurate replacement selection.
Trivalent metal plating provides strong resistance to corrosion and seizing, helping simplify future removal and protect the plug in demanding environments. Corrugated ribs on the insulator help prevent flashover, while the pure alumina silicate ceramic insulator delivers high strength and efficient heat transfer. A copper core assists with heat removal, and triple seals help prevent leakage for dependable internal protection. This spark plug is supplied as a replacement component for compatible applications and should be installed according to the engine manufacturer's service procedures.
