Autolite - Racing Plug

The Autolite Racing Plug is engineered for high-performance racing applications, featuring a 14 mm thread, 0.460-inch reach, and a tapered seat. Its resistor design ensures optimal ignitability and durability under intense conditions. The cut-back ground electrode enhances flame kernel development, leading to quicker starts and improved performance. The yttrium-enhanced alloy reduces ground wire temperature by up to 8%, accommodating performance modifications and handling extreme conditions. Anti-corrosive nickel plating prevents rust, maintaining efficiency and longevity. The high alumina multi-rib ceramic insulator provides superior thermal conductivity and insulation, preventing flash-over and increasing strength. Ideal for professional racers seeking maximum engine performance on the track.
