Champion L82C Marine Spark Plug (Champion 811), Copper Core Electrode

The Champion L82C marine spark plug (Champion plug number 811) is a copper-core replacement plug built for marine engines that see heavy, sustained loads. Champion marine spark plugs are quality OEM replacement plugs, and the L82C uses a copper core center electrode that increases conductivity and gives more precise heat range control, which supports even wear across the plug's service life. The copper core construction is paired with corrosion-resistant plating designed to resist fouling and hold up under the higher cylinder temperatures and continuous-duty conditions typical of marine powerplants, where engines often run at a steady high RPM for extended periods rather than the stop-and-go cycles of automotive use.

This is a dependable, proven design rather than a premium platinum or iridium plug, making it a straightforward, cost-effective choice for routine ignition maintenance and tune-ups. Each plug is sold individually. Confirm the L82C is the correct type and heat range for your specific engine before ordering, since spark plug specifications are engine-specific.
