If it is running good I don't see wasting the money right now. I say if it ain't broke don't fix it.

I couldn't agree more. I would buy 1 as a spare, and when one fails you won't be down a few days waiting for one. You can get towed home put it in bleed the line and be on your way.

I agree. Have a spare on stand by but no need to fix it if it isnt broke

6.7l injectors are coded to the computer, some people are able to change them and have no problems, and some get codes being thrown. Generally on common rail injectors some people say 150k- 200k take them and get them flow tested.

Since I am living that scenario right now, a spare is wise. Make sure it's a good one.

Injectors will last forever if you take care of your fuel

You could always buy another aftermarket set when you can and wait for the stock ones to give up
