Exactly true. A spark's a spark. Unobtainium keeps sparking longer.

right.


the only thing to really worry about with plugs is:

indexing, for old-school plugs

and heat range.


but a spark is a spark is a spark. all it has to do is light the mixture
when the electric power is sent. any crappy (clean) plug will light the mixture.

it is the mixture itself (compression, content, density) that determines the motive power
