Depends. Would you rather do it now and give yourself the peace of mind, or save the money/time for now while taking the chance that they may leak in the next 50-100k miles? There is no better time to replace them, but at the same time, if it ain't broke do you really want to fix it?

My thinking is if it isn't broke don't "fix" it.

Injectors are a few hours, cups are a few days. If I didn't have to do them, I wouldn't. It's no big deal to go back in, compared to what's involved with that project - and the potential to go back in for a failed seal.

If the heads were off and sitting on the bench (like mine are), I'd do it. If they're fine, I wouldn't change them just because I was swapping injectors.

I changed my injectors at 300k and didn't touch the cups because there was nothing wrong with them. Sitting a little North of 490k now. Still running the factory cups.
