Description Technical Specs
Autolite replacement racing spark plugs are the preferred choice for many professional racers. They contain an Yttrium-enhanced alloy, which enables up to 8 percent reduction in side wire temperatures for improved durability and less pre-ignition. Autolite racing spark plugs are available in colder heat ranges than most plug manufacturers to support modified engines. They feature a cut background electrode, which improves ignitibility, and faster flame kernel growth. Autolite racing spark plugs have a nickel plated finish for long life and corrosion resistance. Count on Autolite for the right plugs for racing performance!
