The S55 twin-turbo engine that powers the BMW M2C / M3 / M4 F8X has a horizontally mounted engine oil cooler positioned underneath the center cooling module. This stock engine oil have a tube and fin core which is a bit sensitive construction and therefore it can be damaged by road debris. So with this type of core installed in this position it is not very unusual to get a sudden oil leak caused by a small stone or other debris hitting the stock oil cooler and this can be fatal for the engine.

With our performance oil cooler, we like to offer a much more durable design and of course at the same improve the performance!

To get an exact 3D-model of the available space to design our oil cooler in we did a detailed 3D-scan of the mounting area of the oil cooler. With the help of this 3D-scan model we could design a new performance oil cooler with bar and plate core that improves both cooling and strength. Our design increases cooling area by 20% and core volume by a massive 63% compared to the stock oil cooler.

Our bar and plate core structure is much more robust so it can handle potential road debris better and on top of that better it offers performance!

Significant advantages with do88 engine oil cooler (stock comparison numbers):

- Improved reliability!

- Greater frontal surface area: 1185cm2 (984cm2), 20% larger!

- Greater core volume: 4503cm3 (2755cm3), 63% larger!
