While the original waterboxer injectors were yellow, the newest
replacements I have seen are green.

I am used to Bosch differentiating their injectors by color but green is
what various sources now supply as replacements for 2.1 injectors. I
have installed some and as far as I can tell they work fine. I am
nervous about partial replacement with a different color but the full
sets seem ok. I would like to know if they are similar enough to run
mixed with yellow, if anyone has this info.
