Hey folks,
I am sure the vast majority of us are aware that BMW has revised the injectors for our cars a few times. Recently they released what is known as Gen 2 injectors which are supposed to have been made with different machinery and they are supposed to have improved thermal oil and electronics inside of them. BMW states that those Gen2 injectors should not be mixed in the same bank with the outgoing Gen 1 injector, although I (and many others) have ran gen 1 and gen 2 injectors mixed in the same bank without issues.
The part number for Gen 2 injectors is well know: 13537585261-11, where the -11 stands for Integration Level 11.
Today I went to buy 2 more injectors to keep in stock as I used all of mine up and I discovered that BMW has released new injectors yet again. Their Integration level is -12

Does anyone know what has changed in the -12 injectors compared to the -11? I've never had a -11 fail on me, nor have I seen one being reported as failing online.
