They can be cleaned and tested, but this isn't guaranteed to fix any issues, although it sometimes helps. I think Pelican member witchdoctor does it, and his service is well-regarded.
Flow matching and ensuring a good spray pattern are both Good Things.
Still available new, just not no-brainer cheap...
IIRC, there's a specific warning in the Bosch serviceparts fitment manual regarding the 931 (924 turbo) & 930 CIS injectors, saying that although they may look identical to many other (much cheaper) injectors with similar specifications, they have a special threaded portion to secure the fuel line and prevent it blowing off under boost. Yah, I can see how that would be bad...
The US and RoW injectors have different part #'s too, lore is that the RoW ones flow slightly more.
