1972 Mazda R100 Spark Plugs

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. Built with anti-corrosive nickel plating, they resist rust better than black oxide, 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. With a flat seat type and nickel-tipped electrodes, these performance-grade spark plugs are designed to handle the rigors of racing while maintaining reliability and precision. Whether you’re pushing your engine to its limits or fine-tuning for peak performance, these spark plugs deliver the durability and functionality you need to dominate the track.
