Red injectors could be anything, you need a part number and manufacturer unless you know the exact vehicle they came from. If you know any of those bits of info, just go to any car parts factor and ask their advice on where to go to find some. Alternately, just search for injector reconditioners or sales and USE THE PHONE lol.
If its just G60 injectors you are after btw, get onto Euro car parts, they do list injectors for the PG engine code (corrado G60) although you wont like the price. They should be able to get hold of what you want and you can use the forum discount on them too.
