Though I would share my install of an amazon huge $400 intercooler and a custom trans cooler relocate/ upgrade.
I ordered a tuning performance E60 535d intercooler from Amazon in late July with a 4 week arrival time. I hopped it would come sooner, but they weren’t kidding. Upon initial inspection it appears to be identical to the Wagner EVO for $750. Fin density looks good and the welds are good too. Fitment for the E60s is perfect. Standard cutting of front plastics was required. The connections and location of the hot and cold side pipes is the same as well.
As you can see the trans cooler has been removed, with the stepped intercooler and radar cruise I knew it wouldn’t work. So I hunted down a good cooler and decided to run a fan for the setup. I had to hunt down switched power and figure out mounting and thermostat location. I used a threaded brass thermostat but I will be switching to an in-line 6an cooler soon. (Now that I know the exist.) total cost was about $100 in parts.
Cooler location with mounting. Current thermostat location (still needs a ground). Will be changing to an in-line 6an fitting. Relay mounting point. In line fuse. Switched power from inside Ecu box. Trans cooler line routing.
Let me know if you have any questions. I will update with a final installed photo in a few days.
What size hose and hose barbs were required to splice into the factory trans cooler hoses?

I cant remember 100% I want to say 1/2" 5/8" adapter. I also switched to a 15 row 10AN cooler and 10AN thermostat. I would recommend going with the 10 row 10AN cooler as the 15 row required me to cut into the aluminum bumper.
