I am going to use the Innovate HBX-1 heat sink, together with the Bosch wideband sensor, in the stock O2 location. The heatsink needs to be set according to the airflow. Looking from the front, is the exhaust air flowing from the right to left?

Sorry I don't have a good picture, or I would have posted it with clock numbers around, so it's easier to answer.

 

the holes in the heatsink should line up in line with the DP. not sideways
