Bosch EVO spark plugs are to be produced at the Bosch plant in Bamberg, Germany. They will be available as of October this year in the Middle East and mark the beginning of portfolio expansion. At a first step, EVO spark plugs will be launched for modern gasoline direct-injection engines of Volkswagen and Mercedes-Benz vehicles.

EVO with laser-welded iridium pin on the center electrode
The new Bosch EVO spark plug was developed to ensure reliable ignition of turbocharged gasoline direct-injection engines. In order to make sure it copes with an increase of pressure as may occur in cases of mega knocking, it is particularly robust – thermomechanically, mechanically, and electronically. The laser-welded iridium pin on the center electrode and a platinum plate on the ground electrode ensure its long service life and its high wear resistance.
