Great point about the gap! I gapped the plugs to the OEM spec of .0044 inches. Should I have gapped it wider to get the maximum benefit?
It does matter, because the air in the combustion chamber is moving. This is why new engines have multiple spark events under some conditions.

I would imagine a bigger gap would be beneficial if the spark can make it across. The resistor doesn't change the potential before the spark forms, so a bigger gap won't produce a spark as easily.
