No, it needs oil cooling not additional radiator capacity. Despite what certain people will tell you, on a MT or DCT car, the oil overheats long before the coolant. Look into the stett stg 2 oil cooler or the ER competition coolers. Since you have the aux radiator on the drivers side, the stett might be a better choice.
