Autolite Racing spark plugs are precision-engineered to elevate your engine's performance on the track. Featuring a cut-back ground electrode, these plugs optimize ignitability and enhance 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 conditions. With anti-corrosive nickel plating, these spark plugs resist rust better than black oxide alternatives, ensuring long-lasting durability and efficiency. The high alumina multi-rib ceramic insulator provides superior thermal conductivity and insulation, preventing flash-over while increasing strength. Designed with a flat seat type and mid-projection center electrode, these performance-grade plugs are built to handle the demands of high-speed racing. Whether you're pushing your engine to its limits or fine-tuning for peak performance, Autolite Racing spark plugs deliver the reliability and power you need to dominate the track.
