plugs and gap

I wish (I knew) of a good definitive comparative article. This should be easy to compare on a dyno.

But there has GOT to be a (practical) limit

Bigger plug gaps require lots more ignition voltage and power. Voltage and power is different. Power is power, wattage

Bigger plug gaps at some point must surely get 'so hard' on other components as to be impractical.

RFI......The rf electromagnetic interference caused by high power pulse, IE high power spark

This can be manifested in interference to "it's own system" IE causing misfires, multi-fires and timing glitches due to interference in the trigger mechanism.

It can certainly cause disruption in OTHER systems, including charging and instrumentation

AND it can even cause FAILURE of sensitive systems

Cross firing from one tower to unwanted "other places," including destruction of the rotor (punch through) carbon tracking, actual arcing to ground from various places including the plug terminal itself, or even penetrating plug wire insulation.
