My 3rd gen 4runner has one, as did my stock (race version) Mazda MX-5.
I read that while these are pretty useful to basically bring the oil up to speed faster to reduce cold start engine wear (they bring the oil up to speed by getting it warm against the coolant, which gets warm faster), and also by turning the coolant system's excess heat capacity into a radiator for the oil, too.
I know many are using external coolers for towing, but was just curious, as I've had great engine life out of the last 2 cars above.
