Champion 871 RJ8C Marine Spark Plug, Copper Core, for Evinrude Outboard Engines

The Champion 871 (RJ8C) is a marine spark plug built with a copper core center electrode that delivers increased conductivity and heat control for good overall wear. It is engineered specifically for marine use, resisting the overheating that can occur under heavy, sustained engine loads on the water. The copper core center electrode allows for accurate control of heat range, helping the plug resist fouling and deliver dependable, proven performance over its service life. Superior corrosion resistance helps the plug hold up in the humid, saltwater-exposed conditions typical of marine engine bays. Champion builds the 871 to ISO and SAE standards, giving boat owners a quality OEM-type replacement plug for scheduled tune-ups and engine maintenance. This plug is cataloged for Evinrude outboard engines, making it a straightforward replacement choice when servicing compatible outboards. Champion identifies this part internally as Spark Plug # 871.
