A spark plug resistance element that includes at least one inorganic amorphous oxide and at least one first inorganic crystalline oxide having a relative dielectric permittivity of at most 15. A spark plug that includes at least one spark plug resistance element is also described.

Spark plug resistance element and spark plug

A spark plug connecting element. The spark plug connecting element includes a first contact element and a second contact element. A resistor element is situated between the first contact element and the second contact element. The first contact element and the second contact element have a specific conductivity of 10S/m to 10S/m and the resistor element has a specific conductivity of 10S/m to 10S/m.

Spark plug connecting element and spark plug

A spark plug includes a housing, an isolator arranged in the housing, and a ground electrode arranged on a front surface of the housing on a combustion chamber side. The spark plug further includes a central electrode, a terminal stud, and a resistance element all of which are arranged in the isolator. The resistance element is spatially arranged between the central electrode and the terminal stud and connects the central electrode to the terminal stud. The ground electrode forms a spark gap together with the central electrode. The resistance element contains a resistance material that contains conductive particles and non-conductive particles. At least 80% of the non-conductive particles have a maximum diameter of 20 &#x3bc;m.
