To the OP.
Here's a good read on Troyer's efan kit.

FYI: As far as the original Motorcraft plugs in your truck being standard fare cheap copper, I believe they are actually using double platinum plugs, not copper. Hence the 100k tune up interval they suggest for plug replacement.

I also do think there are probably better plugs available, but I doubt that they will truly provide you enough of a difference to alter your mileage enough to make them worth it.
