Keep every cylinder firing with the Champion Copper Plus Spark Plug (MPN 14, plug type RJ12YC). It drops in as a direct-fit replacement across a large list of classic V6 and V8 applications — from the 1967-1970 Chevrolet Camaro and 1964-1970 Chevrolet Chevelle to the 1959-1966 Buick Electra and many more — and is built to meet OE fit, form, and function.

  • Copper-core precision: the copper-core center electrode allows accurate heat-range control for longer life and dependable performance.
  • Corrosion resistance: the coated shell resists corrosion in harsh environments.
  • Built-in noise suppression: modern resistor technology helps minimize electrical interference that can affect sensitive electronics.
  • Easy to install: the pre-gapped design with a flat seat and an included crush washer simplifies installation.

With a nickel center-electrode tip and a Standard Replacement grade, it's a dependable everyday ignition plug. Quantity per application varies by engine — the listed V8 applications typically use 8 and V6 applications 6 — so order the number your engine requires. Country of origin: China.
