I recently replaced my bosch intercooler pump and I mapped out the fluid flow (hopefully the attached turns up in the post). The fluid goes from the pump to the lower port on the intake manifold. I am posting this, because I want to pursue some upgrades (dual pass option B etc) and due to issues about intercooler pump wiring polarity, and after looking at some of the diagrams from other posts and on zzp website - it wasn't clear to me what the stock setup/orientation was. For me at least - knowing the stock baseline helps me understand the dual pass option B install written instructions (from ZZP).

Hard to tell by your pic but the heat exchanger connections look backwards.
This pic may help.

Thanks for looking - and the picture you show is interesting. However, I stand by my diagram - at least for my stock configuration. See my photo. It appears to conflict with your diagram. This raises the question ... does it matter?

If both of the intercooler inlet/oulet are on the same horizontal level, I don't see why it would matter.

I have ran it both ways through the heat exchanger and I only seemed to noticed the difference when initially bleeding the air out of the system because of the position of the bleeder port on top.

The way the hoses are molded determines the inlet and the outlet. With that said, it doesn't matter as the heat exchanger's inlet and outlet are both on the bottom.

Thx for posting that - because I was curious how it worked internally. So - it is almost fully compartmentalized - except at the top? Fluid fills up the input/inlet/half section first, overflows at the top and then drains out the other half?

Yes just look at the welds. There are 2 separate cores that flow vertically. The end tanks on the bottom are not connected as you can see by the middle weld. The end tank on top is open to and connects both cores.
