Thats the confusing part now. I don't know where specific dealers all source their parts, but everyone always called the Gm ones the "Bosch Remans" direct from Bosch. Now things will be more confusing.
I have not purchased a Bosch LB7 injector, but have Purchased others and they do not come with any GM numbers on the box like the GM LB7 ones do IIRC.
Id say... I spent two months on this and other forums before I bought. I think since its only been two yrs since the change....we'll be seeing failures soon enough.They are still riding the reputation that bosch made for the "GM Remans". Just wait.
How many horror stories u hear of guys having to redo them soon after a 8 pack of injectors. They... the dealer everyone chalks it up to something other than the injector itself. Why would gm want them to get better for the lb7??? so they can sell less of them? I think not imo.... but that's me
