Oil Cooler Kit
Saw a guy talking about this on roadfly. Anyone here with S52 oil cooler experience mind looking at the link below and commenting on this kit and mounting location?

Thanks in advance.

That'd be me--(from Roadfly, that is)...
I just installed the VPD kit and it works well.
If you are standing in front of the car, routing the hoses from the engine bay to the front of the radiator goes through a small opening to the below right of the radiator that has a rubber flap/door. In the engine bay, you can thread the braided hoses between the radiator hoses and the frame, and then cover the braided hoses with the provided nylon cover. I chose to avoid the radiator hoses altogether, but this means you are closer to the alternator (and the drive belt) and necessitates zip-tying the hoses to avoid rubbing on the belt.
Key is doing the braided hoses and connectors right. Basically, it amounts to putting on enough teflon tape on the connector threads and torquing them enough.
On a hot run today, I found a few small leaks (@ 6000+rpm / +55psi) in the connectors to the oil-filter adapter. I retorqued the connections and it looks like the leak has been eliminated. Worst case scenario, I may need to take apart the connectors, re-do the teflon tape and retorque the connections. Probably would need to drain the oil and refill it again.

I could be wrong, but I thought the consensus here was that the modified oil filter cap trick was not such a good idea. I remember reading complaints about a similar (if not the same) one leaking.
The cooler looks easier to install, but why would you not just buy the S54 oil filter housing instead of rigging the filter lid? Price?

Not sure how it works out in the case of an M Coupe, but the first time I put a Sperck-Speck oil cooler on my Healey (mounted in front of the radiator matrix with a space between the two) I created a negative air space and no cooling air flowed between either one (and it overheated as a result). Perhaps BMW also knows this and why they chose to mount the S-54 oil cooler below the radiator and in its own air stream. Now you'll notice the oil cooler's duct opening below the Healey's grill, (my) problem solved.
Nivola, I'm not knocking your system, and I know they're popular, but Dwayne asked for comments. It would be interesting to monitor the matrix temperatures to get the definitive answers and end the speculation.

I think the previous leak issue was with the design of the oil-filter adapter cap itself in its first iteration. This is a newer version of the adapter cap.
The leaks I'm experiencing are due to installer (me!  ) errors on the NPT connectors on the braided oil lines, not the oil-filter adapter cap itself.

Tip on the tape though (from an instrumentation technician): only two (2) wraps and nothing on the first couple of threads. You don't want to introduce little bits of Teflon tape floating through your system (certainly more troublesome on down-hole deep sea well drilling operations & wellheads, but once you learn the proper technique, you stick with it).
Also, taper threads don't necessarily require a lot of torque, especially in soft materials (very easy to elongate the threads and then you, not the fittings, are screwed).
