One of my closest friends is an INTJ, & extremely valuable to me.
We definitely have communication problems, sometimes. It's funny, though. We'll be on the same page about something, but, idk, blame it on the TeFi/FeTi language barrier.. we'll totally miss it. Learn to get around that, and you'll communicate just fine with one another, 99% of the time. I notice that we can both be sensitive to perceived judgements the other party is making, when there may not be any judgement taking place. INTJ's tend to speak in a very absolute manner, and seemingly oversimplify topics of discussion that my Ti sees so many other vital elements hooked together in- which, if I feel strongly about the topic for whatever reason, can lead to some distress about feeling misunderstood.. (sometimes I'll have to stop myself from giving in to kneejerk emotional reactions, like,
does he really think I'm this emotionally weak/does he think I'm stupid- I couldn't come up with these things on my own?/He's missing the WHOLE POINT! DOESN'T KNOW ME AT ALL 
etc etc) & the same goes for how I'll phrase certain things or question certain actions on his part - my wording can at times be perceived as a moral judgement on him- & believe it or not, xNTJ's can be quite sensitive to how their close friends morally judge them. Baby Fi.
Another TeFi/FeTi issue within a friendship can revolve around discussing a problem- often for us it can be about a separate interpersonal issue one of us is experiencing- and the INTJ telling the INFJ how to deal with it most efficiently/effectively, & vice versa. Often, you can be on the same page, ultimately shooting for the same result, but TeFi/FeTi pathways will differ, outwardly, & it's quite easy to lose sight of that, & jump to the conclusion that the other person is making a big mistake, perhaps. Little blind spots, to try to be aware of. Stumbling into this territory can lead back to the aforementioned pitfalls of misinterpreted judgements, etc. Or worse, feeling like the other is trying to control you, which is likely not the case, providing the person you're friends with is an emotionally healthy individual.
Ironically, that very same TeFi/FeTi contrast that can lead to misunderstandings is also what ties the friendship together. You offer the other insight in weaker areas, if you learn how to calibrate your emotional lenses, properly.
Things lost in translation. Misunderstandings happen, but it's all well and good, providing both individuals can communicate, & work that out, in the end. I mean, that applies to any type, doesn't it?
As I said, any NTJ I've had in my life- (I say NTJ because I dated an ENTJ, and we had similar issues communicating as I've had w/INTJ friends) has been incredibly valuable to me, & helped me grow as a person, overall. And I can only hope I've impacted their lives, similarly.
