Do NOT waste your money on Iridium plugs.
They will not last any longer since it has the same ground electrode as any other non-double platinum plug. (Funny they fail to mention that part eh)
Also NO plug will magically generate more power than another properly operating plug. Do not be mislead to believe otherwise.
The best plug to run is a Motorcraft or Autolite double platinum.
They will give you solid operation and the best longevity and are only $3.99 each (cheaper with sales or rebates even)

...oh no you didn't just tell DEMON to do some research... since you're a newbie I'm gonna let it slide..ROUND 1 FIGHT...btw..for Contours you're wrong - do a search.

I'll do the honors. Originally posted by Importslayer:

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".

Woo hoo. Just what I needed tonight.
1. Eh?
On the standard plug there are 2 electrodes: Ground & Center.
On redundant plugs there can be multiple ground electrodes. Do not be fooled by thinking you are suddenly getting sparks jumping to all the electrodes. The spark will still choose the path of least resistance each time.
On a single platinum plug the center (note the word SINGLE) electrode has a platinum button affixed (normally done by laser welding with a notable exception being the POS Bosch injected porcelain tips) to the end of a copper alloy inner rod. The ground electrode is standard treated or plated steel alloy.
On a double platinum plug (note the word DOUBLE) the ground electrode has a platinum button affixed to it in same previously stated fashion.
2. Actually the smaller the electrode the less distance the spark has to jump. The edges are close to the center. This is a reason why there are plugs such as NGK's V-power, AC Rapidfires, ND U-groove, etc.
It is also stated that a fine electrode reduces emissions and can give better throttle response. Hence why the big switch to these style plugs can be seen in newer cars.
3. If that were true in the strictest sense then spark plugs would give you a HP advantage because they improve combustion efficiency. Which of course is not going to happen.
That is correct. A plug's spark is not a factor after full mixture ignition.
No where did I ever state the spark plug itself was not a factor afterwards.
The spark plugs acts as a heat sink for the combustion chamber by pulling heat out into the water jackets. This is why spark plugs have heat ranges.

Importslayer, you need to read carefully and pick your words wisely.

Iridium plugs have iridium at both. Those NGK V are cheap move up the food chain. I will send you a pic of them once I remove them.I'm going to put the Denso Iridium plugs in. You said as long is it fires on time....well thats MY POINT. Iridium plugs fire 0.6 to 0.7 seconds faster I know that doesn't sound like alot but think how fast then pistons are moving. Pre detonation is bad so is late. With these plugs u dont worry about that they fire at the top stroke on time every time at idle or at 7grand I can care less about what you run in your car or what you think works or not a guy was asking what people thought about grounds I told him what I had seen with my own eyes.Like I said to start not all cars will respond the same to that mod(or and other) there all at diffrent stages of performance and mainteance. But I'm telling you grounds do help some cars. I dont sell car part, I'm a jet mechanic I have no reason to hype up a product. I just call it like I see it. I did mistype when I said more electrode I ment bigger. The smaller the electrode the more concentrated the potential at the electrode. Mine I believe are around 0.4mm. Since they fire faster they give a slight edge on acceleration and they have helped with gas consumtpion. So please keep teaching me so that one day I can be a vet like you guys.

Pa did you actually read the whole argument we are talking about ground wires not plug wires...I was using plug wires as an example.
