CSF 8301 High-Performance All-Aluminum Engine Oil Cooler for Select BMW 1992-2002 (Euro Spec)

Fits select 1992-2002 BMW 3 Series (E36) and Z3, including M3, 325i, 328i, and M Roadster/Coupe.

Designed as a heavy-duty upgrade for track enthusiasts and lowered street cars, the CSF 8301 High-Performance Engine Oil Cooler replaces the fragile factory tube-and-fin design with a robust bar-and-plate construction. This design significantly increases durability against road debris and track abuse while maintaining high-efficiency thermal transfer. The cooler features a unique top/bottom dual-pass configuration to maximize surface area and fluid flow within the core.

Finished in an OE-style black to maintain a factory appearance, this all-aluminum unit is fully TIG-welded for maximum reliability. It is engineered to work seamlessly with the CSF #3054 radiator and accepts factory oil-line connections or OE E36 Euro-spec lines for a straightforward installation.
