The NGK LMAR8BI-9 Laser Iridium Spark Plug represents high-performance and reliable ignition technology for modern off-road, adventure, and street motorcycles. Engineered with a precision laser-welded iridium center electrode, this premium plug provides a highly concentrated, consistently stable spark. This translates directly to crisper throttle response, improved fuel efficiency, and significantly easier cold-weather starting. Because the ultra-hard iridium alloy is exponentially more durable than standard copper or platinum, this plug maintains its precise gap over a much longer service life, guaranteeing thousands of miles of dependable combustion in harsh, high-revving environments.
Laser-Welded Iridium Electrode: The ultra-fine iridium center electrode ensures a highly focused spark, drastically reducing the voltage requirement placed on the ignition coil and preventing misfires under heavy engine loads.
Superior Anti-Fouling: Features an advanced alumina silicate ceramic insulator and specialized thermo-edge design that prevents carbon buildup and wet-fouling during low-speed, technical riding.
Extended Service Life: The extreme melting point of iridium minimizes electrical wear and electrode degradation, offering much longer intervals between plug changes compared to standard OEM plugs.
Crisper Throttle Response: A more complete and efficient combustion cycle yields immediate roll-on power and a smoother idle.
Trivalent Metal Plating: The threaded body features NGK's proprietary anti-corrosion and anti-seizing plating, protecting delicate aluminum cylinder heads during installation and removal.
Part Number: 91909
