Champion Spark Plugs Spark Plug, Racing, 14mm Thread, 0.750" Reach, Gasket Seat, Non-Resistor, Brick of 24 (1029S)

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. Service pack of N1043Y plug. 0.120 in. projection, un-plated 600 alloy ground wire, ceramic material, short shell to increase flashover length.
