Product Info

Bosch Copper with Nickel Spark Plugs feature a yttrium-enhanced nickel-copper center electrode for improved durability compared to standard copper plugs. The copper core offers better heat transfer, reducing pre-ignition risk, while a metal-glass fused resistor ensures maximum interference suppression. The ribbed insulator design prevents misfires, and nickel-plated rolled threads resist corrosion, eliminating the need for anti-seise. These plugs are engineered to meet or exceed OE specifications for nickel-copper core spark plugs.
