A batch of spark plugs. Each spark plug has a longitudinal axis, a central electrode oriented in the direction of the longitudinal axis, a ground electrode oriented at an angle to the longitudinal axis, such that a spark gap is formed between a tip of the central electrode and a tip of the ground electrode, and an outer thread for screwing the spark plug in the longitudinal direction into an inner thread of a cylinder head of a combustion chamber of an internal combustion engine, and has an annular contact surface oriented perpendicularly to the longitudinal axis and intended for bringing the spark plug to rest against the cylinder head. After the spark plugs have been screwed into the inner thread of the cylinder head, the ground electrodes have the same orientation with regard to a rotation about the longitudinal axis of the spark plug relative to the combustion chamber.
