Champion Copper Plus spark plugs have been original equipment on a wide variety of engines for many years. These plugs have nickel alloy centers and ground electrodes, with reasonably good wear characteristics. In addition, the extrusion of copper into the center electrode allows for increased conductivity and heat control.

Features & Benefits:
  • Dependable and durable
  • Built to ISO and SAE standards for proven performance
  • Patented SAC-9 semi-conductor resistor for maximum EMI & RFI suppression
  • Copper core center electrode allows for accurate control of heat range for longer life
  • TinTac® and ULTRASEAL shell for best corrosion protection of any spark plug in the industry
This spark plug is pre-gapped, but may require minor adjustments with a Spark Plug Gap Tool / Feeler Gauge to match your engine's specifications. For proper engine performance, gaps should be within ±0.004" of OE-Recommended value.
