Abstract:
A spark plug includes a housing, a center electrode, a ground electrode, and a pre-chamber cup. The housing is configured to thread into a spark-plug hole in an engine. The center electrode extends axially from a center of the housing. The ground electrode extends radially inward from the housing. The pre-chamber cup is attached to the housing. The housing defines a gas thread cavity that extends radially at least partially through the housing.
