Diesel Subaru injectors

[PauSum]

Hi guys, I've owned my 2014 diesel outback for almost 7 years with almost 180,000km on the clock.
Recently I saw a YouTube channel stating "changing the diesel injectors regularly would avoid huge engine repair costs".
Subaru hasn't recommended this to me ( I assume it is not in the service logbook), but is this true?

I've not heard that before; pretty sure it's not included in the service schedule for my Triton either. Changing the injector pipes every 6th time they are removed is part of the Triton service.

Thanks Kevin.
The guy on YouTube states replacing the injectors at a period of every 7 years max!
I'll probably stay with the Subaru service schedule then.
