Hmm, maybe the reason they left it off the X7 is for it to be a little closer to the X5 M50i due to the additional weight. Afterall, I'm sure BMW does not want their top of the line SUV to be much slower than the smaller sibling.

Not sure what the parameters are but I suspect that it may have more to do with the location of the filter in relation to the IM and or the piping leading to. Only guessing, I really do not know.
