3 bar MAP sensor??

[Scott Atk]

Anybody ever used the "Niehoff" or other aftermarket sensors? It crosses to the correct GM part number (1604749)
I need one in a hurry. Checkers can have the Niehoff in a day.
Whatcha think??

I got one from O'rielly auto parts works perfect and has a lifetime warranty.

UPDATE: Received the Niehoff part from Checkers. It is a GM sensor with p/n 12223861 which is the replacement for the discontinued TTA sensor p/n 16040749.
