Has your new sensor not come with the housing then?
I've never needed to remove those screws as the new sensors always came with the housing as they're "calibrated" to the housing's bore/cross section. (Although people do swap housings on modified cars and such when remapping.)
I suppose you might remove the screws for easier claning of the MAF but that's generally in vain anyway.
They're an obscure tool for sure. I bought mine to "be prepared" but i got that wrong.
It did come with the housing, I just figured it was easier to remove those two screws than disturb the air filter and so on. Probably nothing in it. I did try cleaning it when the car was playing up last year, but it wasn't much of a help.
