I have put together an installation guide from an install I did on a 2006 WRX. This is going to be similar for most Impreza and WRX cars that use the H7 bulb type. There will of course be some differences. All in all it is one of the easiest cars to install HIDs into the low beams. There really wasn't anything that caused any issues. The output was also amazing and the cutoff was just as you would expect from the OEM HID projector setup.
You can find the installation guide here:
