but you forgot to say that is for the 2.5L/3.0L V6 while the OP has listed a 2003 4.2L in his sig.
from the specifications book:
for both NA and SC starting from VIN A30645:
4.2 liter All AJ8 4575 (iridium) 0.9 – 1.0 (0.035 – 0.039)
big difference in gap

What gap are they at now? I've never heard of a plug that's reliably 'pre-gapped' no different than a tire that runs at a pressure set by it's manufacturer irrespective of the intended vehicle.
