Product Details

The Champion Copper Plus line focuses on straightforward ignition service with a copper core for stable electrical transfer and heat control. Part number 871 uses a non-removable nut terminal, a single ground electrode, and a resistor design to support reliable spark delivery in older ignition systems. This part cross-references Autolite 124 and Anchor 3522 for the same application. It is a direct-match style spark plug for many vintage Chevrolet Camaro, Corvette, Impala, and Bel Air applications, along with Jeep CJ5 and GMC van fitments listed below.

Installation Notes

Verify the RJ8C plug type, 14 mm thread diameter, 3/8 in reach, flat seat, and the specified gap before installation. Use the listed gap for the application, and confirm the ignition system calls for a resistor plug. Part number 871 is commonly searched for vintage Chevrolet Camaro, Corvette, and Impala tune-ups, so matching the engine specification is important before service.

Quality Assurance

Champion Copper Plus spark plugs are built around a copper core electrode for conductivity and heat control, with nickel electrode materials for steady wear in service. The 871 spark plug follows the RJ8C configuration used across many classic vehicle applications and small engine listings.
