I have been on here for a good length of time and have seen a few threads on here regarding what plugs to put in our 4.6 2V's. The general consensus is that you should replace them with the stock ones however why shouldnt you replace them with anything else? is it just because of the differences in the heat range? or is it the copper vs planium differences?

can i get a Bosch plug with the same heat range and have it perform just as well?

Bosch are poor choice for 4.6

Split and quad fire are for chumps

Platinum lasts and gives good mileage

Copper has a hotter spark but does not last as long as platinum

I would not spend the money for iridium

one of the reasons why most people stay with the motorcrafts because they are fine. i don't any benefit to switch them out unless you have to because of spraying etc.

I like the coppers so I use Motorcraft AGSF-32C which is the stock heat range. Here's some good reading:

I use Motorcraft AGSF-32PM they are the reccommended plugs for the Bullitt. They also have full length threads which may help prevent the blowout problem.

my car seemed to run fine with the stock plugs. So I used the stock plugs again. If it is not broke don't fix it IMO. People have the aftermarket = better mentality and that is just not always true.

copper has a hotter spark, platinum lasts longer. I just did the same plugs as it came with is they were still working fine at 60k I just felt like it was time to change them.

Yes, the "G" plug has full length threads. The old recommended plug AWSF-32PM did not.
