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 enhanced acceleration while improving fuel efficiency. The platinum firing tip resists gap erosion, extending the service life, while the high alumina ceramic insulator provides superior thermal conductivity and insulation for added strength. A multi-rib insulator prevents flash-over, ensuring reliable operation, and the nickel-plated shell offers corrosion resistance for long-lasting durability. Designed with a tapered seat type, these spark plugs enhance performance and longevity, delivering consistent results. With a mid-projection standard center electrode and nickel ground electrode tip, this performance-grade spark plug is built to meet demanding engine needs. Whether you're seeking reliability or improved efficiency, Autolite Platinum spark plugs are a smart investment for maintaining peak engine performance.
