If there is no additional energy fed to the spark plug, the spark will be just as powerful assuming the gap is the same. If they are claiming that they will last longer because they have 3 electrodes I dont beleive that either, because the unused electrodes would gunk up due to their lack of use, so once the one that is being used gets gunked up, itll be time to change the plugs anyway. I've also seen a new plug called pulse plugs or something along those lines. Kind of like an MSD box built into each plug. Those (provided they work) could make a difference, but I would think only in older, carbureted cars.
Wished I would have read your post before writing mine. Anyway, if the spark actually propagates as portrayed in their video then theoretically a better ignition of the a/f mixture could occur. Realistically this is not going to make any significant, or insignificant, difference at all. Now if the electrodes do hold up then it's possible the plug can go over 100,000 miles. Thinking about this, though, raises a question: how does the ECU account for electrode wear vs wear in a normal plug?
And another thought: will your Crossfire be kept long enough, and the plugs last long enough, to justify the extra 6 or 7 dollars they cost?
Well I just convinced myself not to buy them. Syfi, you would be better off keeping your tires properly inflated and routinely replacing your air filter rather than using these plugs.
