Ron,
The latest Grassroots Motorsports says you can as much as double
the factory spec gap, with a "sport" coil. It would depend on
the voltages. They don't explain why, but:
V=IR, so if you're doubling the V (going from a 20KV coil to 40,
say) you can then double the R. The R comes from the plug's air
gap, and it's linear relationship, apparently.
