Champion Racing Spark Plugs

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 pre-ignition from an overheated ground electrode. The spark plugs are constructed with a nickel shell for faster heat dissipation and a copper core (or double core) for further heat removal. Choose non-resistor Champion racing spark plugs for your high-horsepower engine.

Champion Copper Plus Spark Plugs

Champion Copper Plus spark plugs have been original equipment on a wide variety of engines for many years. They feature nickel alloy centers and ground electrodes with efficient wear characteristics. In addition, the spark plugs' extrusion of copper into the center electrode allows for increased conductivity and heat control. Manufacturers have used them in non-automotive applications, such as lawn and garden and other power equipment. Replace your old plugs with Champion Copper Plus spark plugs for maximum reliability.
