Champion RS12YC Copper Plus Marine Spark Plug, Part CCH401, Volvo Penta Compatible

The Champion RS12YC Copper Plus Marine Spark Plug (part number CCH401) is a copper-core spark plug built for marine engines that need dependable ignition under sustained heavy load. The copper core center electrode gives accurate control of heat range, which helps the plug wear evenly and resist the overheating that heavier marine engine loads can cause. The shell carries Champion's patented TinTac and ULTRASEAL coatings for maximum corrosion resistance, an important feature in a marine environment where plugs are constantly exposed to moisture and salt air. A patented SAC-9 semiconductor resistor is built in for maximum EMI and RFI suppression, reducing interference with onboard electronics and marine radios. The plug is manufactured to ISO and SAE standards for proven, consistent performance.

This spark plug is cataloged for use on Volvo Penta marine engines and cross-references to several OEM part numbers used by Volvo Penta, Bombardier, and Ford, making it a straightforward replacement when your engine calls for one of those numbers. It has a 14 millimeter thread and weighs 0.15 pounds. Whether you are doing routine engine maintenance or replacing a fouled or worn plug, the Champion RS12YC Copper Plus offers OEM-level fit and performance in a Champion-branded part.
