The CSF Group A / DTM Race Style Oil Cooler is a direct-fit upgrade for the BMW E30 M3, built on a rugged Aero-Flow bar-and-plate core that is roughly 50% larger than the factory unit for greater fluid capacity and surface area. The lightweight Aero-Flow bars use high-density turbulated multi-louvered fins for improved heat dissipation, with 100% all-aluminum construction, cast TIG-welded end tanks, and a black powder-coat finish. Comes complete with a fitting kit for both OEM-style and -10AN male connections.
