CHAMPION 354

Product Details Attribute

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.
