Bosch Spark Plug

Bosch conventional nickel-copper spark plugs, with a heavy-duty yttrium-enhanced copper core center electrode, are a longer lasting 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
