Brisk Premium ZC is a spark plug that has no grounding electrode and provides three simultaneous sparks per one ignition impulse.
I took that right from the Brisk website. Now how can you have 3 at the same time. Well they have a picture of one sparking. It apears that you have seprate arcs durring the same pulse. The picture shows 2 but it may be able to produce 3. I think what they are calling a spark is really an arc. Just wonder how that would stress the coils and how it would effect the knock sensor ion.
It dose not apear to be like a MSD igniton where it will pulse the plug and you have several seprate spark impulses. This seems to have 3 arc trails per impulse. That dose seem like a good concept for a forced induction motor. I also see a whole learning curve with the tune up and plug read.
