Just thinking about this...what is the average coolant temp? Isn't using hot coolant to cool hot oil somewhat less efficient than using much cooler air, despite coolants much larger heat capacity? Based on that I am thinking that these can't outperform an aftermarket radiator style cooler, but still a nice additional feature for sure.
