NGK Iridium IX Spark Plug LMAR9AI-8D 90526 – EACH

Description

The NGK LMAR9AI-8D Laser Iridium Spark Plug is designed for superior performance and longevity. It features an iridium-tipped center electrode that is six times harder than platinum, ensuring durability and reliable starts. The ultra-fine electrode reduces voltage requirements for efficient ignition. A platinum pad on the ground electrode provides even wear in distributorless ignition systems. Constructed with high-grade alumina silicate ceramic, this spark plug offers excellent heat dissipation and strength. A 98% pure copper core prevents overheating, while a triple gasket seal eliminates combustion gas leakage. Corrugated ribs on the insulator prevent flashover, and the extended insulator nose helps prevent fouling. Additional benefits include improved fuel efficiency, lower emissions, faster starts, and quicker acceleration. The trivalent metal plating enhances corrosion and seizing resistance, ensuring long-lasting performance. The NGK LMAR9AI-8D is best suited for vehicles originally equipped with fine-wire iridium alloy spark plugs.
