Does anyone know what significance has the single digit number stamped all around the injector nozzle? Does it have any relation with precise flow?

Thanks

Nope................All bosch injectors generally have a 10 digit series of numbers to identify them.

X XXX XXX XXX......the last 3 identify the injector for all intents and purposes

I know, on the upper part they have the ten digits with 039 in them since they are for a 2.0, on the other side there is another three digits who knows for what. I'm referring to the injector nozzle, if you remove the green, yellow or black cap, there is a single number stamped a couple of times around the nozzle. I was wondering if it had something to do with fuel flow and matching factory wize. I just removed a old set from a car and all of them had a bunch of 2s stamped under the nozzle cap.
