Did you try and clean it off? MAF sensor cleaner is probably best (lots of other stuff works, but that is the easiest to recommend.)

I'm going to guess it is fine, you have huge amounts of air moving past that so some staining may happen, and as I recall many mafs do have self cleaning cycles so some heating may occur too.

BTW, that little black thing with the two wires is the intake air temp sensor. Engine uses that value along with the volume flow to compute the intake air charge density...just fyi
