Autolite Racing spark plugs are precision-engineered to elevate your engine's performance on the track. Featuring a cut-back ground electrode, these plugs ensure optimal ignitability and superior heat transfer for quicker starts and consistent power delivery. The yttrium-enhanced alloy reduces ground wire temperature by up to 8%, making them ideal for colder heat ranges and performance modifications under intense racing conditions. With anti-corrosive nickel plating, these plugs resist rust better than black oxide, ensuring long-lasting durability and efficiency. The high alumina multi-rib ceramic insulator provides exceptional thermal conductivity and insulation, preventing flash-over while enhancing strength. Designed with a tapered seat type, these spark plugs deliver peak performance in demanding oval and road racing applications. Built for durability and reliability, Autolite Racing spark plugs are the ultimate choice for racers seeking maximum engine output and resilience under pressure.
