What Is This Replaced Part On My Car?

I am thinking it is a "MAP"? sensor, but not sure. Something on my car appears to have been replaced with a used one, because it has red writing on it. What exactly is this? Thanks in advance.

Here is another view of my engine:

Looks like the mass airflow sensor.

Yeah, that's the mass air flow sensor. It probably broke somewhere along the past 14 years and was replaced with a used one. I'd have done the same since a new one is about $900. ;)

that is yourmaf sensor which gauges the amount of air flow to the engine

Thanks for the replies. WOW- $900 for a new one?
