I would be the first to say not to put a front mounted oil cooler using our spin on oil filter adapter. Although the engine is "dry sump", I treat it like a wet sump engine and I don't think the pump is up to the task of pushing the oil to the front of the car and back again. Putting on the S oil cooler is a very smart idea on a non-S car. Laminar flow oil coolers (heat exchangers) like this are very efficient, so I honestly believe that it is plenty.

The only adapter I use with the spin-on oil filter adapter is an accusump single-port input adapter to put an accusump on the engine for the track, coupled with a shorter Napa Gold 1081 stubby oil filter to maintain ground clearance.

My wife's W8 passat uses the same laminar flow oil to water cooler as the S, which is the same as the one used on the side of the tiptronic transmission. It's widely shared among many models.

I've noticed that in traffic that some of the added heat is for sure from the tiptronic slipping the torque converter (versus putting it in N while stopped), so automatic cars for sure would benefit from a low temp thermostat even more since there is more heat being pumped in and getting full coolant flow earlier is a great thing.
