Autolite Racing Spark Plugs are used by many professional race car drivers. These spark plugs contain an Yttrium-Enhanced Alloy, which enables up to 8 percent reduction in side wire temperature for improved durability and less pre-ignition. Autolite racing plugs are available in colder heat ranges than most plug manufacturers to support modified engines and feature a cut background electrode for improved ignitibility and faster flame kernel growth. They are also nickel plated for a long-lasting, corrosion-resistant finish. Since its inception, the Autolite brand has provided the automotive aftermarket and Original Equipment manufacturers the highest quality ignition products. Autolite has been in operation for over 100 years and has produced more than 11 billion spark plugs and glow plugs.
