In theory, enlarging the gap forces the coil to send a "hotter" spark which,
in turn, ignites the air/fuel mixture more efficiently. This has worked in
the past on numerous vehicles and is a trick that's older than me. ;)
Try .045" for a little bit and then pull the plugs out and regap them to
.040" (factory)..but check the mileage in between to see if there's any
changes.
Remember, no two engines are exactly the same from the factory so the
results might be different from vehicle to vehicle. (That's why some
vehicles run faster than the other identical...you can blame QC for that one
at most production plants.)

Oops, sorry! '00 V6.
Again, I might just be over-sensitized, you know, looking for some
difference (and so imagining it), but the feeling I got was that idle was
slightly rougher and the truck didn't pull quite as hard off the line and
through that 2500-3500 RPM range where I can really hit it. But if .045
should be fine for stock ignition and wires, I'll go with it and assume it's
just my imagination. As a diagnostic, I should end up with worse mileage
results if it's not burning efficiently, shouldn't I?
