Bosch Auto 7905 Bosch Nickel with Copper-Core Spark Plug

Heavy-duty yttrium enhanced nickel-copper center electrode ensures superior reliability and durability for up to 50% longer performance life vs. standard copper plugs. Copper core provides broader heat range to resist pre-ignition and fouling. Nickel-plated rolled threads provide superior resistance to corrosion and do not require anti-seize - saving time. Angled, ribbed insulator design prevents misfire due to flash-over. Metal glass fused resistor maximizes interference suppression. Bosch conventional Nickel-Copper Spark Plugs are designed to deliver performance and value. Heavy-duty yttrium-enhanced nickel center electrode with copper core provides a longer lasting copper core spark plug. Engineered to meet or exceed Original Equipment specifications for nickel-copper core spark plugs.
