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, better acceleration, and improved fuel efficiency. The platinum firing tip resists gap erosion, extending service life, while the high alumina ceramic insulator enhances thermal conductivity and insulation for added strength. A multi-rib insulator prevents flash-over, and the nickel-plated shell offers exceptional corrosion resistance for long-lasting durability. Designed with a mid-projection standard center electrode and nickel ground electrode tip, these spark plugs deliver reliable performance under demanding conditions. Engineered in the USA with over a century of expertise and backed by the sale of over 11 billion plugs, Autolite Platinum spark plugs are a trusted choice for drivers seeking enhanced engine efficiency and durability.
