Having looked at my own bumper (stripped the front of the car two weeks ago ready for some refreshing) there aren't any special 'lugs' to attach the ducting at the bumper end, so I can only assume that they must have a specific part number (attached my makeshift ducting via cable ties to the fog light fittings)
It is something I have looked into as I constantly cooked the brakes on my old 2.0 DTI as well as my 2.2 Direct.
Granted they are standard size (milk bottle tops) but there is a definite benefit to any extra air you can get to the wheel wells to aid brake cooling. BMW have been fitting brake ducts to standard models for over 30 years along with VW having large cut outs in the lower front bumper/arch liners on standard Golf's and Passat's for a long time now.
Mid 90's Polo's had a fin on the caliper and the lower arm to direct air inside to the disc as standard fit on 1.0 models too.
I made some front tubing into the front outer grilles on my old Saloon and ran them through to the wheel wells (through the arch liners with a hole saw) but they were to small a diameter to make any difference)
The Vectra V6 facelift, as far as I know, all have ducting, be it SRI bumper or not.
Admittedly, I could be wrong with all, but all that I have looked at have anyhow

The 2.8 was not available as an SRi only Elite trim Vectra wise and all auto too, Signum well Watchman's 2 Signums are both Design if im right which is a kind of SRi i think as it seems the sportier out the lot. But i know they all had 314 brakes as only the VXR had the blue 345's there are no plain 345 calipers available. Most Signum 2.8's are auto as well, its very rare to find a manual, all talking about facelift though as they didn't do a preface 2.8.
