Injector louder than others

In my cold start thread I posted a vid of a clicking/clacking/knocking/tapping noise I was hearing in the cab. The noise was most noticable at crusie with no load on the engine.
I listened with a stethoscope and it seemed to be coming from the passenger side valve cover near the back. When I had the VC off to replace GPs I used the stethoscope with the engine running. The sound was heard the most on top of the back fuel injector. I unplugged the injector and the sound stopped. Now this injector is different from the others, the other 3 are black with Ford numbers, the back injector is Orange with a big R on it.
What do you guys think? Is this injector bad? Is something mechanically wrong in this cylinder? Or is this injector just really loud?

the only injector that should have been different is on the drivers side on cyl #8 so it sounds like you have a swapped injector thats sure got an issue... if money isnt too much of an issue i'd get an OEM injector and put it in.(lots of vendors here sell them). may have an aftermarket one that isnt exactly quality.

I was not expecting to see the orange injector for sure. Is the loud noise from it a sign of not performing or just a trait of this injector?
