Looks like the Altima guys are having problems with their MAF's too, and based on a quote on pg2, they've got a different sensor, but similar prognosis...

i think that part number is for 2k2 and up, possibly for vq3.5. One of the member here with an 2k2 replaced his maf with that same part number. I do know that there is another part number flowing around, i think thats for 00-01. correct me if i am wrong.

 

See this thread for the part number information.

I researched this myself, and had the actual parts in-hand to compare them.
