IF i remember correctly the air vents/grills are bigger on rs2 maf, look like a waffle.
the s2 maf is much more restricted with smaller holes for the air to get in, so definitely not the same aesthetically, but function the same mechanically.''I'm 999 thou' short of a mill!''

Here are graphs of the AAN and RS2 OE MAF output voltages at different RPMs on an AAN engine:

The difference on that graph is likely because not two brand new units were compared and because they are within a 3% error margin anyway.
That graph to me looks like they used an AAN maf with some miles on and a brand new ADU MAF.

It will fit, but I don't know if it will work on a proper way..
