Actually I am questioning how effective the OEM style cooler is in the first place. This picture I found of an OEM cooler from an Integra shows that the oil coming out of the engine goes straight through the cooler without being forced through the heat exchanger. Look at the rectangle hole (where the oil enters the cooler), you can see right through it. And the oil coming out of the filter goes straight back to the engine. What am I missing here?
