ABOUT THIS PRODUCT

Autolite Platinum spark plugs are crafted for exceptional 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 firing tip prevents gap erosion, extending the 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 superior corrosion resistance, these spark plugs deliver reliable, long-lasting performance. The extra-long projection of the standard center electrode design, combined with a nickel ground electrode tip, optimizes ignition for better acceleration and reliability. With a tapered seat type and integrated resistor, these performance-grade spark plugs are engineered to meet the demands of your engine while providing excellent value and durability.
