When I searched for an used MAF sensor for my 2004 Maxima, I get plenty of MAF Sensors in ebay for the price range $57 - $90. After Market ofcourse.
AFM is the brand name.
Anyone has experience with after market MAF sensors ? thanks guys.

 

For something like that, get OEM.

 

Thanks for the reply. Ya, I was also skeptical on after market sensors, just wanted to check before I make any "mistake".
