I don't see how you can break a MAF with 'too much' air, its only a heated wire at the end of the day that is cooled by the airflow over it, which allows a certain voltage to the ECU.
The MAF even has a 'clean' cycle at the start of each drive, it shoves massive current through the wire to burn off any crap. So it shouldnt be dirty (unless its getting oily from KN oil which won't burn off).
Now correct me if I'm wrong but the MAF fails because the hot wire gets thinner over time with all the heating and cooling, just like the elements a toaster. So its bound to fail over time - are you guys using brand new OEM replacement sensors? If not then you're using a part thats had years of use and is probably ready to fail anyway.
The only way I can see different filters killing a MAF is this - less filtration so more grit can 'hit' the hot wire as air is sucked through, which could be wearing it out quicker - that may be completely irrelevant though.
With the map sensor, yes I believe it would've been used to control the VNT, as they're used along side MAFs in VNT'd diesels. You can run without one without any issue except EML in a Golf for example though, as the MAF is more relied upon.
