Autolite Racing spark plugs are meticulously crafted to deliver peak performance in 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 and increasing strength. With a tapered seat type, these spark plugs are tailored for intense racing applications, whether on oval tracks or road courses. Engineered with a durable design and nickel-tipped electrodes, they are built to withstand extreme conditions while maintaining consistent performance. Perfect for racers seeking reliability and maximum engine output, these spark plugs are a top-tier choice for competitive motorsports.
