Minor snake oil. Oil is more of an insulator than conductor of heat. As
it cools on the surface of a can or inside an oil cooler, the slightly
thicker viscosity will cause it to flow slower than the oil inside the
passage thus creating an insulating barrier. This is why fin and tube
style oil coolers have internal spirals to help stir things up. Flat
plate style coolers with multiple parallel paths work best.

Hey does anyone know if these oil filter coolers
really make a difference?

JC Whitney:
"Convert your oil filter into an oil cooler and save
hundreds of dollars on engine repairs and replacement!
Collars work like a heat sink to lower oil temperature
to safe water temperature level"

Thanks
