I don't know if we will ever get a clear answer to this. I talked to an NGK rep a while back and he couldn't confirm that they were the same exact plugs as OE. He could only tell me what their website said, which was that the NGK Laser Platinum #BKR6EQUP plugs are
Original Equipment Manufacturer, and/or Original Equipment Service Part.
I guess if you change your plugs every 40-60k or so, you can use the BKR6EQUP from trusted retailers with confidence they will work fine.
He was able to tell me the NGK Iridiums, that many here use, only last half as long as BMW OE plugs.
