that was hot... not as chaotic as I expected..

My guess is they used fiber optics with a twin plug head, other plug fires normally. Thoughts..?

Seen it before, but still very cool to watch!

Almost looked like pre-ignition
 

The fuel looked like it was burning a fair amount of time before the piston reached the top of it's stroke... But then maybe I just don't know enough about an internal combustion engine to know what it's supposed to look like. It's just the one thing that I noticed.
