Bosch Copper with Nickel spark plugs feature a heavy-duty yttrium-enhanced copper core center electrode for improved durability.

50 percent longer life than traditional copper core spark plugs.
Exclusive Yttrium extruded copper core center electrode increases resistance to spark erosion.
Tapered, v-profile nickel chromium ground electrode for consistent performance and prolonged service life.

MAXIMUM PERFORMANCE: Every Double Platinum spark plug is necked-down center electrode fires quicker and cleaner, with less voltage for easier starts and quicker acceleration. Full copper core electrode provides better performance in all conditions.
IMPROVED DURABILITY: Our spark plugs are platinum-to-platinum firing for superior durability and super conductive Yttrium enhanced ground electrode provides superior heat transfer.
CONSTRUCTION: These spark plugs are platinum enhanced high nickel alloy side electrode maintains precision gap and assures virtually no gap erosion for longer plug life.
high nickel alloy side electrode maintains precise gap.
AUTOLITE ADVANTAGE: Autolite has been producing spark plugs since 1936 making it one of the most trusted and reliable brands for your OE replacement spark plugs needs.
