that thing below the filter w/ the hose coming out of it is the oil cooler:



It's the same one they use on auto foresters, Forester XT, the H6 and other turbos like the WRX.

I read somwhere that there was a cooler so I looked it up. I saw the diagram for this in the service manual. I was a little confused about how it cools the oil. I was expecting something with hoses to a radiator and thermostat/valve control flow into the radiator. Is there a tech here with some knowlege of how well this thing works?

It uses the thermostat from the radiator. It's a fluid to fluid pancake type cooler. It uses the coolant rather than air like I think you were thinking. It alternates layers of oil and coolant. I installed on on my RS some time go. Here are some closer pics:

I think it does a good job. It's nice because the car warms up faster so in the winter you have heat quicker, nice bonus But in that case I suppose it's working as a coolant warmer and not an oil cooler

That's nice to hear... I was always worried about aftermarket rad-style oil coolers over cooling my oil in winter time.

Do you know if it also has a power-steering fluid cooler? I haven't checked, nor ordered my shop manual yet.

Quality oil coolers the air to fluid type have thermostats to prevent overcooling AFAIK

Not sure about the PS fluid but I don't think so.

I am installing an oil filter adapter for my oil temp and oil pressure sensors. As this is after the oil cooler, is this going to make my oil temp readings artificially low?

That depends on whether you're looking for the oil temp coming from the engine, or the oil temperature going to the engine on the next pass.

Either way, you're getting a relative measurement from which you can base tuning on in the future. It should serve your purpose.
