I have this plug and play AEM Series 2 for a 2005/2006 Subaru WRX STI. It was plugged in car and removed within 1 week

It is in perfect working condition 

What you see in pictures is what you get.

Reason it was not used is because someone told the owner that he needed this ecu and a Cobb accessport, so he decided to keep the Cobb AP to be emission compliant.

AEM #30-6821 and retails for $2042.04

So it's a killer deal for a quick sale.
