CSF Group A / DTM Race Style Bar/Plate Oil Cooler (8218) for 1988-1991 BMW M3

Fits 1988-1991 BMW M3 Base.

The CSF 8218 Group A / DTM Race Style Oil Cooler is engineered for BMW E30 M3 owners requiring superior thermal management for track use or high-performance restorations. Utilizing an extremely rugged bar-and-plate design, this cooler provides significant durability against road debris compared to standard tube-and-fin units. The core features CSF’s proprietary Aero-Flow bar design, which reduces weight while maintaining structural integrity and maximizing airflow through the unit.

Efficiency is driven by high-density turbulated multi-louvered fins that increase heat exchange rates. With a core approximately 50% larger than the factory unit, this upgrade significantly increases both fluid capacity and surface area for heat dissipation. The 100% all-aluminum construction features TIG-welded cast end tanks and a durable satin black powder coat finish for a discreet OEM appearance behind the grille.
