These Champion racing spark plugs position the spark approximately 1/16 in. into the combustion chamber and feature colder heat ranges that use a shortened ground electrode. This is designed to aid in exposing the spark to the air/fuel mixture to help prevent preignition from an overheated ground electrode. Champion racing spark plugs are constructed with a nickel shell for faster heat dissipation and a copper core or double core for further heat removal. Choose these non-resistor Champion racing spark plugs for your high-horsepower engine.
