Default engine oil cooler replacement

Have anybody tried to replace C2N1169 oil cooler with a newer one 7W836A642CB for 2006 and later cars?

dneu,
I looked into it but aborted when I discovered the different connection orientation.
The X100 Cooler (C2N1169) connects at the top but the X150 Cooler (7W836A642CB) connects at the side. This means you have to fashion an additional 90 degree bend in the hoses. You cannot just simply twist the rubber hose by this amount due to risk of damage and leak.

I was thinking of modifying or bending those holding tabs to mount the cooler horizontally. I found a supplier in the UK who is willing to ship to the US. Waiting for a shipping cost quote.

Mounting the heat exchanger core horizontally is unfavorable because it will greatly reduce it's cooling efficiency.
All the Tubes in the matrix will not benefit from the forced ventilation air-flow. Less heat will be rejected and the oil temperature at output will be higher than design intent. In a continuous circuit, the entire volume of oil will overheat.
Why source an X150 Oil Cooler?

I was considering making a "lip" that would force the air through the core... but it is over since I found a supplier in the UK
