NGK Spark Plug Stock # 6801 (Snowmobile)

The NGK Spark Plug Stock # 6801 (BR10EIX) is an iridium spark plug engineered for premium ignition performance in snowmobile engines. Built with NGK's Iridium IX technology, this 14mm threaded plug delivers consistent spark reliability in cold-weather conditions where standard copper plugs often falter. The 0.749-inch reach and gasket seat design ensure proper fitment and secure sealing in your snowmobile's combustion chamber, while the resistor construction suppresses electromagnetic interference for clean engine operation and electrical system compatibility.

Iridium electrodes offer significantly longer service life than conventional materials—typically 2 to 3 times the lifespan of standard copper plugs. This durability reduces replacement frequency and contributes to stable combustion timing across extended operating hours. The precise electrode gap maintains consistent ignition voltage, which is critical for snowmobile engines that operate across wide temperature ranges and varying atmospheric pressure at elevation. NGK's manufacturing standards ensure tight tolerances that translate to reliable starting in subzero conditions, a fundamental requirement for winter sports enthusiasts.

This plug is designed for snowmobile operators and winter recreation users who depend on predictable engine performance in extreme cold. Whether you're maintaining a vintage sled or a modern high-performance model, the BR10EIX provides the electrical durability and thermal stability needed to prevent cold-start hesitation and mid-ride misfires. Proper spark plug maintenance is foundational to engine longevity; replacing plugs at recommended intervals with NGK OEM-equivalent components ensures your snowmobile starts reliably and runs clean season after season.
