I need some input here.
My ER sports oilcooler, which replaces the stock OC on the passenger side with a bigger core, is about to arrive. Right now I have the AR Design OC in front of the radiator but found oil temps to rise too high.
Now I don't know if I should run both OCs in series, or if I should get rid of the AR OC to free up airflow to the radiator, which may be useful since I'm AT.
What do you think works best?
