Yes you are probably right. I have not seen a number from a manufacturer. You have a link? Some people need to follow the manufacturers recommendation to help them sleep at night. They are good suggestions but I don't spend anymore money than I need to keep mine safe and running good. Mine were not in that bad of shape with 300K on them but I decided to change them to improve the mileage a little and reduce the smoke.
It is more important to look at your mileage, starting issues, idle, and exhaust smoke than some number. Sure if you have a lot of smoke and loud idle at 120K then change them. It also depends on the quality of fuel you get too. A good filter and water trap should really help the injectors last a lot longer than 120K.
