The real reason for the 2 extra plugs is that they balance the charge of the other plugs. When you pump 5-10 thousand volts through a plug, it creates a negative charge in order to fulfill the laws of energy conservation. Similar to when you drop something in water, the water will fill in where it was displaced, and shoot back up some. If it wasn't for the law of energy conservation (lec), the water would fill in and flatten out, without a splash. Then anybody would be able to make an olympic dive. Anyhow, the secondary plug fires right after the first one, to eliminate the negative backwards energy, thus fulfulling the lec in a way such as to produce the least amount of heat/damage to the coils. As an added benefit, it also burns some extra fuel that did not combust, although the time between the two sparks is very small. Also, due to little inefficiencies, such as resistances in the wire and coil, the second plug will not fire as powerfully as the first.
This is why most engines are an even number of cylinders.
