I don't know if they sell them seperately or to the US or whatever.
But they have coated oilpressure pistons. That first link claims that they are DLC coated (for €80 when fitted with their rodbearingservice), which is a very very wear resistant coating.
Most germans speak English I think, for sure if money is to be made...
My guess is that they are m50 pistons. Those pistons are also used in the s52 oil pump and the euro s50b30. When the s50b32 (euro) came out bmw stopped listing those parts but my guess is that the design didn't change.
Lots of parts this deep in an engine dont change the complete lifecycle of an engine family (for instance the m54 still has the same rodbearings as the 1972 m10 engine, thats why you can pick up a set for 20 bucks).
Just a thought
