On the '08+ STI MAF (P/N 22680AA380) the pin-out is as follows (looking into the connector on the MAF side, with the retaining tab up, left to right).

 

1. Temp Signal

2. Ground

3. Power

4. Ground

5. MAF Signal

 

Not only are the mounting ears mirrored - the shoulder with the o-ring groove is a larger diameter on the '08+ STI MAF, and cannot be installed in '05-'09 LGT/OBXT housings.

Thank You! I'm not using it on a Subaru though. I'm using it on a Nissan Altima Turbo project. Everything is installed but the stock Nissan MAF is teh suck.

'08+ STI got a new style MAF sensor that has a slightly higher threshold. You should be able to see the P/N molded right on the face of it.

Thank you but that doesnt quit answer my question. I gather that the STi uses a different MAF sensor than the WRX? And are the pinouts still the same as the picture? The metal ears are reversed (180degrees) on the sensor that I have.

This listing is from right to left for your picture.

1. Power (Yellow/Blue)

2. Ground (Black/Green)

3. MAF Signal (Red/Blue)

4. Temp Signal (Yellow/Blue)

5. Ground (Yellow/Green)

Sorry to reopen an old thread but I found it through a Google Search because I am using a Suby MAF Sensor for my Nissan Altima Turbo.

Are these listing the same for the 2012+ Imprezas? And are the MAF sensors the same between the STi and WRX's? I bought a 2012 STi MAF Sens0r
