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 prevents gap erosion, extending service life, while the high alumina ceramic insulator enhances thermal conductivity and insulation for added strength. Designed with a multi-rib insulator to prevent flash-over and a nickel-plated shell for corrosion resistance, these spark plugs deliver long-lasting reliability. The tapered seat type further boosts performance and durability, while the extra-long projection of the standard center electrode design ensures optimal ignition. With a performance-grade type and nickel ground electrode tip material, these spark plugs are built to meet demanding engine needs. Whether you're seeking enhanced efficiency or extended durability, these spark plugs are a dependable choice for maintaining peak engine performance.
