do88 replace the S65 M3's factory oil cooler with a 10 row bar and plate core using a high density offset fin design. Core volume rises to 5247 cm3 against the original 3105 cm3, a 69% increase, and active cooling area to 7728 cm2 against 4858 cm2, a 59% increase, while the cooler itself holds 13.9% more oil. In do88's back to back testing under the same conditions, oil temperature after the cooler dropped from 103°C to 84°C. The oil line connections and brackets are CNC-machined so the cooler drops into the OE brackets and lines without modification.
