Autolite - Racing Plug

The Autolite Racing Plug is engineered for high-performance racing applications, featuring a 14 mm thread, 0.708-inch reach, and a tapered seat. Its non-resistor design ensures maximum conductivity, while the cut-back ground electrode enhances ignitability and heat transfer for quicker starts. The yttrium-enhanced alloy reduces ground wire temperature by up to 8%, accommodating performance modifications and intense conditions. Anti-corrosive nickel plating prevents rust, maintaining durability and efficiency. The high alumina multi-rib ceramic insulator provides superior thermal conductivity and insulation, preventing flash-over.
