Abstract: This patent application of Utility Model refers to a spark plug of the type that has a diode positioned between two portions of the core (3), being said diode (2) disposed internally to the ceramic body (4) of the spark plug (1); the diode (2) acts with the purpose of improving the conduction of the electric current that crosses the spark plug and reaches its electrode (9); said spark plug (1) differs from the spark plugs that belong to the state of the art due to the fact that the unit diode (2) is mounted between two conical concave connectors (A) and (B), of which one has a spring (M) incorporated, thus enabling the mounting of diodes (2) of different diameters and lengths; the use of a tubular spacer (E) is optionally provided to enable the use of diodes (2) of different diameters on such way that the diode (2) is kept correctly positioned, centered within the hole of the ceramic insulator (4); this patent application of Utility Model further provides a diode (2?) having two contact ends (C) where at leas

Abstract: Process for assembly of a diode in a spark plug cable of an internal combustion engine, suppression spark plug cable connector, manufacturing process of a suppression spark plug cable connector, spark plug connector and spark plug connection socket of internal combustion engines, said process being part of a spark plug cable (2) which is cut and receives a pipe sector (7) assembly inside which a diode (8) is located, the pipe (7) is bond between segments (2?) and (2?) of the spark plug cable (2) and receives around it a pipe-bridge (4) and a heat shrinkable cover (5); the connector (A1) featuring a diode (A2) in its inside, mounted in an encapsulated way (A2?); another connector (B1) being provided as a main cylindrical body (B2) made of injected material inside which two metal inserts (B3) are mounted in a centralized and mutual opposition arrangement, each of said inserts having a mutual contact terminal (B4) and in its respective opposite ends, a self-tapping-shaped screw terminal (B5); the socket (C1) pro
