Champion CCH415 Copper Plus Marine Spark Plug, RN9YC

The Champion CCH415 (RN9YC) Copper Plus Marine Spark Plug is a quality OEM-style replacement spark plug built for marine engines, including Evinrude outboard applications. It uses a copper core electrode that improves conductivity and heat control, helping the plug wear evenly over time and resist fouling. The shell carries Champion's patented TinTac and ULTRASEAL coating for maximum corrosion resistance, an important feature for engines that run in wet, salt-exposed marine environments. A patented SAC-9 semiconductor is built in to suppress EMI and RFI interference, which helps keep onboard electronics running cleanly. This spark plug is manufactured to ISO and SAE standards for consistent, dependable performance, and it is engineered to resist overheating under the sustained heavy loads typical of marine engine use. Whether you are doing routine maintenance or replacing a worn or fouled plug, the Champion CCH415 offers a straightforward, direct-fit replacement backed by Champion's established manufacturing standards.
