We usually when we see these cars now religiously end up removing plugs and scoping each injector which reveals all re leaking injectors, poor injector spray pattern and injector's not closing down when instructed to do so.
But re these yes if you're going to encounter this sort of problem replace all injectors, plugs and where necessary coils. But plugs due to contamination/possible contamination and injectors seems the way forward on these I'm afraid if you're looking and a confirmed injector related issue

Hi Steve. Do you think the latest index 11 injectors are better or are you still seeing them leak? I don't know what the changes are between iterations but to me it seems that the piezo crystal wears down so the tolerances change. In which case every index is likely to be garbage.
