I recently purchased a new set of Bosch Platinum plugs for my '98 GL to replace the Motorcraft Platinum already in my engine. The problem is that I can't get them to thread. Autozone verified that I was given the correct part # (#4205). I spoke w/ a guy with SP Motorsports that told me I needed the Bosch Platinum +4's (#4458) and that I was given the wrong ones.
I was able to remove and re-install the old ones easily. Is the problem with the threads or do I have the wrong plugs? Are the +4's really worth $5 ea.?

Duratec engines require double platinum plugs, so stick with Motorcraft or Autolite plugs. The Bosch +4's are very hit-or-miss, and many people have reported problems after switching. The Autolite part number is APP764; I paid $3.99 each at Checker Auto (or Kragen or Schucks or Advance or CSK... all the same thing).

Stick with Motorcraft or Autolite double platinum plugs as hetfield says.

For several months now I have been using Bosch paltinum plugs. Regular stuff, not 4+. So far no problems. I will keep an eye on them for the following months just to be on the safe side. NGK's are really expensive here (like 65$ for a set of six) and hard to come buy. We have Ford dealership coming to Sarajevo this fall so maybe I can get some Motorcraft (I gues I can order it too but I am being lazy) just to be sure. I firmly believe in OEM for a non-moded engine. If one does the mods, well everything is a fair game then.

I have been using the same Bosch +4s for the past 52,000 miles. Took them out for inspection a few weeks age and they still look very good.
Engine performance is still very good as well as mileage. I will certainly consider another set come change time!
