Abstract
The present invention pertains to a spark plug jacket, e.g. for a large or high performance combustion engine, and a corresponding method of manufacturing a spark plug jacket, in particular to provide an improved sealing towards a coolant cavity. Accordingly, a spark plug jacket is suggested, comprising a contact surface for contacting a support surface of a cylinder head of a combustion engine, wherein in a first state, when a spark plug is not mounted in the spark plug jacket, at least a portion of the contact surface of the spark plug jacket defines a first angular offset to a contact surface direction defined by the support surface of the cylinder head and, in a second state, when the spark plug is mounted to the spark plug jacket, said portion defines a second angular offset, wherein the first angular offset is larger than the second angular offset.
