Autolite Double Platinum spark plugs are engineered for exceptional durability and performance, making them an ideal choice for distributor-less ignition system (DIS) engines. Featuring a platinum-to-platinum design, these spark plugs effectively prevent gap erosion, reduce misfires, and extend service life. The yttrium-enhanced ground electrode ensures superior heat transfer, allowing the plugs to withstand high temperatures and pressures for greater longevity. A high alumina ceramic insulator provides optimal thermal conductivity and dielectric strength, while the multi-rib insulator design prevents flash-over for reliable operation. With a mid-projection center electrode and platinum tips on both the center and ground electrodes, these plugs deliver consistent performance and efficiency. Backed by over a century of engineering expertise and a legacy of over 11 billion plugs sold, Autolite guarantees proven quality and reliability. Designed for performance-grade applications, these spark plugs are a smart upgrade over copper and standard platinum options, ensuring your engine runs smoothly and efficiently.
