Abstract
The present teachings provide for a spark plug for an internal combustion engine and a method of constructing the spark plug. The spark plug can include a housing, insulator, first electrode, and ground electrode. The housing can be configured to be coupled to the engine. The insulator can be received in the housing. The first electrode can be received in the housing and can be spaced apart from the housing by the insulator. The ground electrode can have a first end, second end, and base portion. The first and second ends can be coupled to the housing for thermal conduction with the housing. At least one of the first and second ends can be coupled to the housing for electrical conduction with the housing. The base portion can be spaced apart from the first electrode to define a spark plug gap between the first electrode and the base portion.
