Autolite Copper spark plugs are designed to provide reliable performance and durability, making them an excellent choice for your vehicle or application. Featuring a copper core center electrode, these spark plugs ensure optimal thermal control and resistance to fouling, while the high nickel alloy center and ground electrodes deliver extended life. The extra-long projection of the center electrode enhances ignition efficiency, and the nickel-plated shell resists corrosion for long-lasting durability. With a high alumina multi-rib ceramic insulator, these plugs offer superior thermal conductivity and insulation, ensuring strength and reliability under demanding conditions. The flat seat type and built-in resistor further enhance compatibility and performance. Ideal for quick starts and consistent power, these spark plugs are a dependable solution for maintaining your engine's peak performance.
