Not sure what finalizing would be. Every injector I've ever seen, made or tested here has all the parts and laser markings on them. Here is one I'm working on now...notice the Bosch emblem in the corner, "927" is the Charleston Plant, 12 is for being made around noon on Line 16, date on the bottom, part number on the terminal housing. The other side says NISSAN and has a few other markings.To my knowledge Bosch no longer offers Injectors with their name on it? I know all Injectors are Bosch cores but they are handed to 3rd party vendors and they "finalize " the Injectors .
