Works on 2016 Subaru Outback 3.6R
Delphi AF10345 Mass Air Flow MAF Sensor. I was a little skeptical about buying a non OEM sensor. This was not the cheapest offering and not the higher price of a Denso OEM maf. Installed on my Ouback with 90k miles. This was the first day after installation and about an hour of highway/local driving. I was surprised at the smooth acceleration and power. I now realize my old one was failing but not throwing any codes. To my surprise I gained 2 to 4 mpg. I'm hoping hoping it will last. I'm keeping my old sensor just in case. LOL.

Quality part as advertised
Exact fit for 2009 Subaru Forester 2009 xt. Has been working well for weeks. Appears to be genuine name brand part.

This unit still performing months after installation.
This unit actually manufactured in China under Delphi specifications has demonstrated excellent performance for months now after ordering for 2017 Subaru Forester 2.5i. For less than half the price of the OEM part.

Defective part
Defective. Replaced on my Subaru Impreza and reset the check engine light. A few days later it came back on for the Mass air flow sensor.

MAF sensor worked perfectly!
I ordered this MAF sensor to repair my mother's Subaru forester. I worried about the part just not working out. I am really glad I ordered it and got a great deal thanks to Amazon warehouse. Part arrived yesterday and 10 minutes later it was installed and the car is starting again should have ordered this last week and saved myself a hassle trying to get one locally at 4 times the price. I wouldn't hesitate to order this sensor again.

The original Denso MAF Sensor dies after 12 years on the Subaru Forester. I was planned to get a OEM Denso one but switched for this Delphi MAF Sensor due to the price is 1/3 cheaper than the Denso MAF Sensor. My Forester is back to normal and not jerking when in acceleration. Strongly recommended for Subaru Forester owners.
