Champion CCH818 Marine Spark Plug - Copper Core, Resists Fouling

The Champion CCH818 is a marine spark plug built as a quality OEM replacement for inboard and sterndrive engines. It uses a copper core electrode that improves conductivity and gives precise control over heat range, which helps the plug wear evenly and last longer under continuous marine use. The design is engineered specifically to resist overheating during heavy engine loads, a common stress point for boat engines that run at sustained high RPM for extended periods.

Beyond heat management, the Champion CCH818 is built to resist fouling, so it maintains a cleaner firing tip and more consistent spark over time compared to plugs without this feature. Champion also states this plug delivers superior corrosion resistance, an important trait given the damp, salt-exposed environments marine engines operate in. Overall, the CCH818 is positioned for dependable, proven performance rather than a premium or performance-oriented tier, making it a straightforward replacement plug for routine engine maintenance and tune-ups.
