Autolite Racing spark plugs are precision-engineered to deliver peak performance under intense racing conditions. Featuring a cut-back ground electrode, these plugs optimize ignitability and 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. Built with anti-corrosive nickel plating, they resist rust better than black oxide, ensuring long-lasting durability. The high alumina multi-rib ceramic insulator provides superior thermal conductivity and insulation, preventing flash-over while increasing strength. Designed with a tapered seat type, these spark plugs ensure optimal compatibility with aftermarket cylinder heads commonly used in oval and road racing. With a short projection center electrode and nickel-tipped materials, they are tailored for high-performance applications, delivering reliable ignition and durability on the track. Perfect for racers seeking maximum engine output, these spark plugs are built to handle the demands of competitive racing environments.
