Autolite Copper spark plugs are designed to provide reliable performance and durability, making them an excellent choice for maintaining your vehicle's efficiency. 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 long projection design of the center electrode enhances ignition performance, 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 tapered seat design and built-in resistor further enhance compatibility and performance, making these spark plugs a dependable solution for quick starts and consistent power.
