can we talk plug gaps?

I pretty much agree with TrailBeast on this. Ignition systems are a "funny thing." The conditions of combustion and the spark gap determine the voltage at the plug, which is loading down the "open circuit" voltage which that particular system can output

So as you open this gap, and as the voltage goes up, the STRESS on the entire secondary system--- coil, rotor/ cap, wires and plugs, gets worse. This of course is the very reason that OEM went to larger plug wires---better insulation.
