Default RE: spark plugs

From what I have learned about the system it is sort of a fail safe spark system. You have a single coil over each cylinder which fires one plug directly underneath it into that cylinder, in addition to firing one of the two spark plugs on a different cylinder. Both the local plug as well as the remote plug fire at the same time. The only thing that is unclear is if these coils actually fire twice during a single 4 stroke cycle. That would make the most sense since that would serve two purposes. For one it would provide redundancy for all 8 cylinders in that the cylinder would have the plugs fired by two different coils which would be unlikely to fail at the same time, and two, it would aid in burning un spent fuel and help to clean up the exhaust emmisions.

I am continuing to search for the answers to this as I am also very interested.

Take care,
