Having now researched this plug, I would not touch it with a 10foot pole.
MP called out so that others don't make the same mistake when following their recommendations.

As an Indy shop installed gapped (aka non approved BMW parts) I would assume BMW to be happy of having another excuse to avoid paying anything.
Champion plugs (used as OEM parts by many manufacturers) normally do not just disintegrate without reason (otherwise you would have heard of the class action law suit) and destroy engines so you must have had a damaged set/ fake plugs/ damaged during gapping/ damaged during install.
Just because he offered his opinion on the brand doesn't make him responsible. It is your car and your decision. You went with MP so you knew your warranty was voided. Then you decided to install new spark plugs (without any needs as it sounds you didn't run into misfire etc.).
If the boost blew your engine or constant misfire did ..... then I would look to MP but for this?
