I'll do the honors.

OK, that's got me confused. Are you saying the Autolite Platinum Pro plugs I am running has more than TWO electrodes (lead and ground)? Because if so, I missed it completely on the set when I gapped them - must be an optical illusion?

Hah, close to actually making a point. In actuality, the smaller the gap, the less voltage is required to jump the air gap - the bigger the air gap, the higher the resistance seen in the circuit requiring more voltage to complete the circuit (given the same current flow).

Anyway, the DIS ignition system in the Duratec (and the Zetec) is MORE THAN STRONG enough. Ignition upgrades are not necessary or worthwhile on our cars because Ford over-engineered the ignition system.

According to Demon??? You just don't understand - this is according to the laws of Physics. Once the spark has ignited the air/fuel charge, the combustion reaction is self-perpetuated - the remaining air/fuel mixture is heated to its ignition point by the heat generated by the reaction of the currently burning air/fuel mixture. If this wasn't true, and spark was needed to complete combustion, the spark would be continued for the entire power stroke on every four stroke Otto Cycle engine ever manufactured, which isn't the case.

OK, next time you change plugs - they don't last forever, do they? - measure the gap and compare it to the gap you set before installation. I can tell you that on the set of NGK V-Power I ran for 12,000 miles (copper core, non-plat), the power lead looked fine on all six, but the ground electrode was visibly worn (in my estimation, at least 5 mils) on the back bank three. Since your overpriced, overhyped Iridiums use exactly the same material on the ground electrode as the cheap, plain jane V-Powers, you will experience the same phenomenon. Amazingly enough, without the protection of Iridium, my power leads looked acceptable but in the early stages of wear.

Go do some research on "waste spark DIS ignition" and you'll understand why (maybe). Just know that the back bank fires backwards on the Duratec.

Well, a plug isn't a plug - that's our point. Our ignition system most certainly needs a plug with platinum on the power lead and the ground. Not Iridium on the power lead only, not platinum on one side only and FOUR non-platinum ground leads, not copper core with platinum on no leads at all.

You will learn the hard way that a plug isn't a plug (and I seriously doubt Demon ever said that), and that you do need to worry about gap erosion on the back bank plugs when they aren't protected with a platinum surface.

One final tip: Don't run around here challenging the people here that know what they are talking about and can back it up with fact, especially when you argue your point with fallacy. This isn't CLubSi - we debate based on data and information, not marketing hype and "feelings".
