Look at the photo of the BavAuto site I posted above. Although both Bosch plugs say FGR7DGQP, they have different part numbers for the OEM plugs and the Platimum 4 Plus plugs even though they are both labeled FGR7DGQP. Do you see what I mean? I would guess that although NGK makes OEM plugs, they (just like with Bosch) make other cheaper plugs that will fit, but are not OEM. The OEM recommended plugs from both NGK and Bosch are two or three times as much as the cheaper ones from the same brand.
Here are the exact plugs recommended by BMW for your 03 4.6is. Notice both supplemental part number don't match up with what Amazon has as their part #

I get your point. And if it truly is a different plug, I don't mind paying more for it. But if the plug is really identical but they use 2 different PN's and the only difference is price, well that is another matter.
Does anyone know if NGK really makes 2 different plugs under the BKR6EQUP number?
I checked with my local auto parts store and they sell the same PN BKR6EQUP for $9.95 and it is listed as the "OEM plug". Whatever that means.
