i did alot of this kind of research getting into my N55 x5 knowing of all the 135 upgrades that are available trying to figure out what would work as far as downpipe and chargepipe intake etc.
Realoem.com is your friend.
compare parts.
i just did for you on DP and chargepipe and the OEM part numbers are NOT the same.
on intercooler.
the OEM x5/x6 intercooler is actually quite larger than the E9x/E8x OEM IC.

while that doesnt mean efficiency, its hard to tell if its worth an upgrade (or for you transfering over).
for my N55 x5, its all F10 535 performance parts, ER DP and chargepipe, BMS f10 intake etc.
im running cobb stage 2 and the FMIC seems to be holding ok.

maybe the x6 N54 is like the z4 n54, or maybe the e60 n54.
cross reference the z4 (as the e60 is older so i doubt it) as i know the z4 has specifically made DPs and CPs for it i believe by ER or maybe it was a different company.

goodluck
