What is this spark plug? A Plasma?
I want to get it a partner for my twin.

I'd say that's a Rimfire VR2.

I'd say you are right...VR2. I think I'll get one of those little guys to better scale for my Silver Bullet, and to make a little more clearance between the plug and the valve gear to minimize possible arcing. I will post my ingnition system here for feedback from this group.
