Fitment Notes

• On twin-cylinder KTM LC8 models (1050, 1090, 1190, 1290 series), this plug fits the inner cylinder only - a second plug, NGK LMAR7DI-10 (96956), is required for the outer cylinder
• On single-cylinder KTM/Husqvarna 690 and 701 models, this plug is the only plug required (1 per motorcycle)
• Twin-cylinder models require 2 plugs total: 1x LKAR9BI-10 (95371) + 1x LMAR7DI-10 (96956)
• Pre-gapped at 0.039"-0.040" (1.0mm); verify against your bike's service manual before installation
• No automotive fitment - motorcycle application only

Product Description

The NGK 95371 (LKAR9BI-10) is the Laser Iridium spark plug for KTM's LC8 parallel-twin and LC4 single-cylinder motorcycle platforms, spanning the 690 Duke/Enduro R/SMC-R, 1050 Adventure, 1090 Adventure R, 1190 Adventure/RC8, 1290 Super Adventure/Super Duke GT/Super Duke R, and Husqvarna 701 series. On twin-cylinder LC8 models, this plug fits the inner cylinder only - the outer cylinder requires a separate NGK LMAR7DI-10 (96956), so two plugs of different part numbers are needed per motorcycle. On single-cylinder 690 and 701 models, one plug per motorcycle is required.

This plug installs as a direct OEM replacement with no modifications required. The fine-wire iridium center electrode delivers reliable ignition across the full rpm range, from street riding to aggressive adventure and track use. Always confirm inner vs. outer cylinder designation for your specific model before ordering to ensure correct plug selection.
