The Champion Copper Plus spark plug line leads the industry in innovative performance benefits. Copper Plus spark plugs stand out from other spark plugs, thanks to their extra hard and dense ceramic insulators. The ceramic insulators allow for flawless functionality with high-energy ignition systems while maintaining extremely accurate heat ranges. The spark plugs also feature an extruded copper core in the center electrode. This enables accurate control of the heat range, which is important for maximizing the performance and longevity of the spark plug. A patented semiconductor resistor protects against RFI (radio frequency interference) from on-board electronics and assures maximum plug life. The zinc-plated shell uses TinTac and ULTRASEAL, a patented process that eliminates the need for spark plug antiseize compound. ULTRASEAL provides the best corrosion protection of any spark plug in the industry. Copper Plus plugs feature a 2-year unlimited mileage manufacturer's warranty.
