Champion CCH592 Spark Plug (RJ12C, Champion #592) - Copper Core, Chrysler Outboard

The Champion CCH592 spark plug is Champion's RJ12C plug, also identified by Champion as spark plug #592, and is offered for Chrysler outboard applications. It uses a copper core electrode that increases conductivity and improves heat control, helping the plug wear more evenly over its service life. The CCH592 is engineered to resist fouling and to provide superior corrosion resistance, giving dependable, proven performance in an outboard's demanding operating environment. Champion designed this plug to resist overheating under heavy engine loads, which is important for outboard engines that run at sustained high RPM. The plug is built to ISO and SAE standards, the same benchmarks Champion applies across its small-engine spark plug range, and it is an OE type replacement plug rather than a generic substitute. The CCH592 carries a Bombardier OEM equivalent part number, so owners of equipment originally fitted with that Bombardier plug can order the CCH592 as a direct replacement. Each package contains one spark plug with an 8 millimeter thread. Whether performing routine maintenance or replacing a fouled or worn plug, the Champion CCH592 restores original ignition performance using Champion's own manufacturing standards.
