The CSF x Rogue Engineering Race-Spec Oil Cooler uses a robust bar-and-plate construction in a top/bottom dual-pass layout for the BMW E46 M3 and E39 M5, far stronger than the factory tube-and-fin design under track abuse. It features 8 rows of cooling with a high-density multi-louvered fin pitch, fully TIG-welded extruded end tanks, and a motorsport silver finish. It is a drop-in fit using factory oil-line connections and OEM radiator brackets, and follows the OEM bumper contour for clean splitter clearance.
