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 the service life, while the high alumina ceramic insulator enhances thermal conductivity and insulation for added strength. Designed with a long projection standard center electrode and a nickel-plated shell, these spark plugs resist corrosion and deliver extended durability. The multi-rib insulator prevents flash-over, ensuring reliable operation, and the tapered seat type offers a secure fit. With a performance-grade design and nickel ground electrode tip material, these spark plugs are built to meet the demands of high-performance engines while maintaining consistent reliability. Whether you're seeking enhanced efficiency or long-lasting durability, these spark plugs are a dependable choice for your vehicle.
