E3 Spark Plugs E3.56 Autolite Copper Core Spark Plug with Leak-Proof Seal, Pack of 1 Spark Plug

The Autolite Copper Core Spark Plugs are designed to deliver quick starts, improved fuel economy, and smooth acceleration for your vehicle. These spark plugs feature a copper-glass seal bonded insulator, terminal post, and center electrode that ensure a 100% leak-proof seal. The full copper core electrode enhances heat transfer, promoting longer plug life and better engine efficiency. Crafted with high alumina ceramic for high dielectric strength and a robust steel shell for easy installation, these spark plugs are built to last. The multi-rib insulator reduces the risk of "flash over," preventing misfires, while the copper core center electrode offers superior thermal conductivity. For extended durability, the spark plugs are engineered with a high nickel alloy center and ground electrode.
