Champion Copper Plus 954 Spark Plug

Champion Copper Plus 954 is a spark plug built for dependable ignition performance in small-engine and classic vehicle applications. It uses a copper core electrode for improved conductivity and heat control, with nickel center and ground electrode materials for steady wear characteristics.

Compatible with 1972-1973 Porsche 911 and 1972 Porsche 911 applications listed below, this RN57YCC plug supports the specified resistor setup and gap requirements for those vehicles.

Key Features

  • Copper core electrode for conductivity and heat management
  • Nickel center electrode tip and nickel ground electrode core material
  • Resistor type spark plug
  • Flat seat design with 0.75 reach
  • 14 mm thread diameter and 0.813 hex size
  • Pre-gapped at 0.025 in (0.64 mm)
  • Champion Copper Plus small engine classification
  • Part number 954 / plug type RN57YCC

Product Details

The Champion Copper Plus line focuses on practical ignition performance with a copper core that helps transfer heat efficiently while maintaining consistent spark delivery. For Porsche 911 owners working with the specified 1972 and 1973 applications, Champion 954 provides the listed resistor configuration, flat seat, and RN57YCC plug type needed for proper service replacement. This part cross-references Anchor 3195 and CSF 3830 for the same application.

Common Issues This Spark Plug Can Address

  • Hard starting caused by worn or fouled spark plugs
  • Rough idle from inconsistent spark delivery
  • Misfire symptoms related to incorrect plug gap or worn electrodes
  • Reduced ignition efficiency from aged secondary ignition components
  • Heat-related plug wear in service intervals that demand stable thermal control

Installation Notes

Verify the vehicle calls for RN57YCC and the listed gap specification before installation. Check the gap against the application requirements for your Porsche 911, since the fitment notes list 0.024 in for 1972-1973 and 0.028 in for 1972. Confirm thread diameter, reach, seat type, and resistor type match the engine specification before tightening.

Fits 1972-1973 Porsche 911, N/A. Fits 1972 Porsche 911, N/A.

Quality Assurance

Champion Copper Plus spark plugs are built around a copper-core design with nickel electrode materials to support consistent conductivity and heat control in service.
