There are probably many reasons for the fact that a lot of FFR's don't have the
oil cooler. On mine it didn't fit in the original budget and after driving the car I found that the
oil temperature always stayed close to the coolant temperature anyway. So no need for extra cooling. They do look cool and if I am ever looking for somwhere to spend that extra $400 (that I don't have) the cooler would be a nice addition.
