Dinan High Capacity Oil Cooler System - BMW 135i 2013-2011 135is 2013
Controlling operating temperatures becomes even more significant when you consider increasing boost pressure, which in addition to added power output also generates more heat. Recognizing the significance of this issue, Dinan set out to develop a more efficient heat exchanger, ultimately in the form of a High Capacity Oil Cooler. The Dinan High Capacity Oil Cooler provides literally twice the volume of the stock unit and that's really just the beginning. Nicely integrated inlet ducting provides greater airflow efficiencies and the ventilation of air to the fender well has also been improved with a larger outlet. The system mounts neatly in the stock location and includes lightweight convoluted PTFE hoses with polyester outer braid fitted with race-quality fittings.
Specifications Total Volume Stock: 9.5 oz. / Total Volume Dinan: 19 oz. Stock Surface Area: 45 sq./in. / Dinan Surface Area: 67.5 sq./in. Stock Cooling Tubes: 10 / Dinan Cooling Tubes: 23 Stock Tube Length: 90 in. / Dinan Tube Length: 207 in. Stock Tube Area: 112.5 sq./in. / Dinan Tube Area: 414 sq./in.
The results of the oil cooler upgrade are quite significant, with the temperature gauge holding steady even under high load/high boost scenarios. And for those of you who track their cars, even occasionally, the Dinan oil cooler is a must.
