Autolite Platinum spark plugs are crafted for superior performance and durability, making them ideal for older engine applications. Featuring a platinum center electrode firing tip, these spark plugs ensure quicker firing, smoother starts, and improved fuel efficiency. The platinum design prevents gap erosion, extending service life, while the high alumina ceramic insulator enhances thermal conductivity and insulation for added strength. A multi-rib insulator minimizes flash-over, and the nickel-plated shell resists corrosion for long-lasting reliability. With a mid-projection standard center electrode and tapered seat type, these performance-grade spark plugs deliver consistent ignition and optimal engine operation. Designed with a nickel ground electrode tip and integrated resistor, they provide dependable functionality for a wide range of vehicles.
