I had a thread a few weeks ago about doing the plugs on my MKZ with the 3.5L Duratech.
Normally I follow the rule of "If it has a spark plug, it gets an NGK" and I've never been steered wrong with that.
With that said, I do plugs on modern stuff so rarely given how long they last that I don't necessarily keep up with what's "best" on precious metal plugs.
I've kind of always gone by the thought that a good quality correctly gapped precious metal plug(whether platinum, platinum-irridium, or some other alloy) is probably perfectly fine and that the fancy multi-electrode plugs were more gimmicky than practical(although I'm open to being wrong about that also).
Looking a bit, Rock Auto presents me with quite a list of options and with a small enough difference in price until you get to super exotic ones that I wouldn't lose any sleep over it(i.e. $3 vs $4 isn't going to kill me). I'm guessing the Motorcraft fine wire platinum is probably closest to OEM, and my inclination would be to go with the NGK standard platinum. Still, though, I'm wondering for you all, if this was your vehicle, what would you choose? There again, I'm not going to lose sleep over $3-5 a plug, and I'd buy anything on this list if I'd see a benefit from it since, after all, $8 each is still under $50 for the whole car.
