[RICE RACING]

You know when you petrol foul a plug, the car will misfire is bad enough at light cruise, your EGT will go up and it mostly happens on the trailing spark plug as the fuel easily gets trapped in behind the blind plug hole.

it's a catch 22 you run the right heat range for full power and if you cruise it too much or have not enough load you will foul a plug, this is mostly the reason the CD was instituted @ mazda for competition engines, anyone running a Peripheral Port will tell you that who has lived with one as a daily (I did for about 7 years) but back then was ghetto spec and could not afford SFA let alone a don mega CD set up.

On a lean fuel setting 15:1 or weaker you will see the CD will fire better and more consistently compared to Inductive, all round I say my experience is its a better system of ignition, but again like all good things it costs ca$h.
