Just bringing up my old dead post... But any new choices out there for spark plugs for our 3v 5.4L? I've been doing some searching, and all I'm coming up with is Champion, Motorcraft, E3, Autolight, Pilot, Ford Racing, and Roush... which is the same old same old. I've heard something about NGK coming out with something, but nothing is indicated on their website. It's time to change them again...
I don't know about you guys, but I only seem to get a solid 40k-50k miles out of my spark plugs. After that I start getting rough idle and low grade missing. I guess on the bonus side, I never have to deal with the carbon buildup problem... lol

^^^ Good time to start thinking of replacement anyway. Ford specs 60K, but gap growth is rearing it's head around there.
I've found that, if you R&R every 30K or so, it almost does not matter what you use

You are lucky. I think you are the first to report no problems in Ford engine.
