All right, drove to work with the 2010, didn't see much improvement, only about +3°C. I think I need to block off the stock air intake path into the engine bay and rig the end of the dryer hose a little closer to the catalytic converter and maybe block off other airflow into the engine bay from other spots.
*EDIT*
Blocked the air intake path with some aluminum tape, looked at lower grill block situation, looks like black foam is the way to go down there.
