4.8is parts used on the 4.4i?

I'm hunting down the last few gremlins right now on my X5, and coming up with some odd results.

I have a Camshaft position sensor fault, so I'm looking for the replacements.
I know that my intake cam sensor on bank 2 (drivers) is this part.

But the site says that I should really be running 4 of these guys:

I know this isn't the case because I've just been through it all, and the wiring loom for intake cam sensor on bank 2 has a fuel injector style connector on the wiring loom on top of the fuel rail, so it is pretty specific.

Also when diagnosing a belt problem, my PS pump is the same as the is pump and not the adjustable found on the 4.4i (typically).

Was there some mid-model year changes on the N62 in this build date, or did I get a frankstein parts car from factory or is the online db's just incorrect?
