Spark Plugs with a copper core deliver quick starts, smooth acceleration, and improved fuel economy.
The bonded insulator, terminal post, and center electrode with a copper-glass seal ensure a leak-proof tight seal, while the full copper core electrode optimizes plug life and improves heat transfer.
High alumina ceramic is featured in Copper Core Spark Plugs for high dielectric strength, and a robust steel shell aids installation.
The danger of misfires is reduced by the multi-rib insulator, and the center electrode with a copper core offers higher thermal conductivity.
These spark plugs are engineered with a center and ground electrode made of high nickel alloy for extended life.
