Unique spark plug with auxiliary electrode at insulator tip created using patented laser application technology.

!!! Replacement interval: as recommended by the engine manufacturer / maximum see table below.

Application of the latest Brisk ?patented? technology and knowledge of engine managements transformed into Premium EVO spark plug series. Especially better utilisation of fuel energy, reduction of specific fuel consumption and suppression of some imperfections of new and older engines. (For example: the impact of regulation on the engine operation). The patented technology application of auxiliary electrode coating to the tip of the insulator ensures the unique properties of the spark plugs. The alignment of the individual indicated medium pressures and the displacement of their diameters to the upper limit in the final consequence increases engine power. The reduced voltage requirement from the ignition system expands their use.
