Where to tap into for aftermarket oil cooler install

[Dasky_spas]

On newer G series, many non M don't come with a dedicated oil cooler or transmission cooler. Given bmw don't use a threaded oil filter, we cannot easily use the standard thermostatic AN adapter to feed the cooler.

For those with experience, where would be the best place to feed the cooler? Some kits have model specific BMW to AN fitting part but still unsure where the lines would source from. There's an oil heat exchanger mounted to the block so I was thinking to remove the line exiting the heat exchanger and run that line to one of the AN conversion pieces. No clue how this should look but input would be handy.

Same question applies to the transmission too- where to tap into?

I believe the engine oil has a heat exchanger.
Ditto for the charge cooler.
So an auxillary radiator will be better.

The car already comes with the oem dual radiator setup, plus the two aux coolers for the charge coolers. It's just missing the trans and oil cooler.
