I have been told that our ignition system is fairly weak when compared with the single coil aftermarket systems like for the old 4.6's and 5.0's. Our coil packs tend to degrade after a year or two. Hence why we have to run a tight plug gap (e.g. 0.035") to keep the spark from blowing out.

Although you may be correct about the coil packs degrading, that is probably not the main reason for tight gaps. It wouldn't surprise me that they are a "wear" item, they live in a tough environment.

Antoher thought:
Probably the best bet is to simply use the copper version of the stock plugs, the 12c's. Copper will pull more heat out of the cylinder unlike platinum/iridium, and you are still using OEM parts to stave off anyworries with something like a blown sparkplug or anything else they might try to blame on it.
