People run the Porsche 928 MAF as an upgrade. I may have one for sale here soon.
E-mail me if interested. Keep in mind that this MAF is not cheap though. Also, it requires minor modifications to run it.

Maybe some people. Most people are either OE S4/S6 or RS2 MAF equipped even with...
RS2 and larger turbos. Maybe Hap or Cody upgraded their MAFs - but I don't think so. Of course, now, Hap, is running a MAF-less control system.

Yeah, I should have been more descriptive. Not many people use an MAF as big as the 928.
It is completely overkill unless you are running a larger than RS2 turbo. Someone like Hap, Cody or possibly Emre with his new turbo would benifit from it. As Urs4boy mentioned, Hap is not running his engine with motronic anymore so he has no need for it anymore. Unfortunately, I don't have the MAF with me right now, so no luck with the diameter. I do know that it is about 35-45% larger though.

There are several other options also:
I have heard of people using Sport Quattro MAF, M5 MAF (almost equal to the SQ maf) or cheaper, mounting the original MAF into a 4" housing. The last method is OK if you are going to remap anyway.
Then there is always the option of mounting the original MAF after the turbo, on the pressure side. That will usually also require a remap, but I have heard of people not remapping. Should be put after the IC though.

I'm loving the GT3071 turbo, just got finished with that and a 'stromung gen 99' install, more on that later. Yes, I know I need a heat shield.,
