Dinan High Capacity Oil Cooler System E90 335i (Cars without factory oil cooler)

It's no secret among 335 owners that while the cars perform admirably, they tend to run a bit on the warm side. This appears to be true even with the cars equipped with the factory oil cooler; and in case you weren't aware, not all 335s came with an oil cooler at all! For those who drive the cars in a spirited fashion on a regular basis, this issue is even more pronounced. While this is certainly a concern in stock form, it becomes even more of an issue when you consider increasing boost pressure, which in addition to added power output also generates more heat. And when you back your products with matching new car warranty coverage, including consequential damages, you tend to be a bit more concerned about the real world ramifications of increased turbo boost pressure on the car as a whole. 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. Two complete systems have been developed, one for vehicles that weren't equipped with a factory oil cooler and the other as an upgrade for the stock unit. Now every 335 driver has the opportunity to lower operating temperatures significantly, providing peace of mind as well as avoiding that notorious inchlimp inch mode when things get simply too hot.
