The S55 mounts its engine oil cooler horizontally under the centre cooling module, where the factory tube and fin core is exposed to stone chips and road debris, and a punctured cooler can end the engine. do88 3D-scanned the mounting area and designed a bar and plate replacement to fill it, a far more robust core structure in that position. Frontal surface area rises to 1185 cm2 against the original 984 cm2, a 20% increase, and core volume to 4503 cm3 against 2755 cm3, a 63% increase.
