BMW530i

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.

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.

1. Power (Yellow/Blue) 2. Ground (Black/Green) 3. MAF Signal (Red/Blue) 4. Temp Signal (Yellow/Blue) 5. Ground (Yellow/Green) http://i193.photobucket.com/albums/z151/Legacy_NSFW/Intake/MAF.jpg 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
