Brisk is a good choice - you *may* need a colder plug (or just use the one they specifiy for stock/light mods) - it's one piece and if you don't mind R&R every 20K or so - go for it.
[EDIT] - I just reviewd the available heat ranges - you'll likely be okay with the 3VR17YS:

Otherwise - OEM. But R&R those more frequently than the retarded 100K interval as well.

I just put the new E3 Diamond fire plugs in mine, e3.70 for the 5.4. I will never put the two piece plugs in it again, what a PIA to remove them. I just did this over the weekend, but I can tell the idle is smoother.
Just FYI, someone posted last week that those had failed. Had some pictures. I think it was an earlier engine, not the 3v. I would look for the thread but don't have time right now. Keep an eye on them.

Did a quick search (I don't have lot of time either) and didn't find anything, would be interesting to know how they failed, LMK if you find it. Who ever came up with the two piece MC plug was a IDIOT.
