There's nothing in the world saying the rest of ur injectors are gonna crap out,,, as long as u change ur oil faithfully. And watch ficm voltage, and have the blue spring, and have the 12mm stand pipes n plugs, and keep clean fuel filters, and drain ur separator.

U know if you've been relaxed with the maint,,, that would be my deciding factor for how many injectors to do.
