Autolite Racing spark plugs are precision-engineered to deliver peak performance under the most demanding racing conditions. Featuring a cut-back ground electrode, these plugs ensure optimal ignitability and superior heat transfer for quicker starts and enhanced engine efficiency. The yttrium-enhanced alloy reduces ground wire temperature by up to 8%, making them ideal for colder heat ranges and performance modifications. Designed with anti-corrosive nickel plating, they resist rust better than black oxide, ensuring long-lasting durability. The high alumina multi-rib ceramic insulator provides exceptional thermal conductivity and insulation, preventing flash-over while increasing strength. With a tapered seat type, these spark plugs are optimized for aftermarket cylinder heads commonly used in racing applications. Built to withstand intense conditions, their durable design ensures reliable performance on the track. The nickel center and ground electrode materials further enhance their resilience, making them a top choice for racers seeking maximum engine output and efficiency.
