Champion CCH71 Copper Core Spark Plug (RC12YC), OEM Equivalent Part 71

The Champion CCH71 (RC12YC) spark plug is a Copper Plus formulation built for dependable ignition performance and long service life. Its copper core center electrode allows for accurate control of heat range, giving the plug good overall wear characteristics and consistent firing under load. The plug's construction inhibits corrosion and helps resist fouling, and it is built to ISO and SAE standards for proven, repeatable performance.

The CCH71 uses a 14 mm thread size and ships pre-set to a 0.04 inch electrode gap, so it is ready to install without additional gapping in most applications. Champion backs the plug with a 2 year unlimited mileage guarantee or the manufacturer recommended change interval, whichever comes last (commercial or performance usage is excluded). Each unit weighs 0.15 pounds.
