CSF Swap Race-Spec Oil Cooler - BMW S54

The S54 swap has become one of the most popular upgrades for the E36 chassis — but adapting the cooling system to handle it hasn't been easy. CSF built this oil cooler specifically to solve that, drawing on their deep experience cooling both the E36 and E46 platforms. Anyone who's tracked an E46 M3 knows how fast oil temps can climb, which is why CSF partnered with Rogue Engineering to build the proven Dual-Pass Race Spec Oil Cooler (#8032) for that chassis. It works on S54 swaps too — but its size doesn't allow owners to retain factory A/C. This new cooler solves that: shorter on the right-hand side, it lets you run A/C lines in the OEM path while delivering the same dual-pass, 8-row, turbulated Bar/Plate performance as the #8032. Both coolers use the S54 OEM oil-line connections, and CSF also offers a fitting adapter kit for -10 AN lines (#8241) for those running custom setups. Features Unique top/bottom dual-pass design for maximum surface area and flow Fully TIG-welded extruded end tank design for superior reliability and durability Turbulated heavy-duty Bar/Plate construction for maximum reliability 8 rows of cooling with a high-density multi-louvered fin pitch Designed to work with CSF's S54 Swap All-Aluminum Radiator (#7211) Motorsport Silver finish Accepts factory oil-line connections For S54 swap vehicles with air conditioning (A/C) — for non-A/C setups, see CSF #8032 Fitment For use with CSF Radiator #7211 Year Range Make Chassis Model Trim Engine 1998 BMW E36 323i - 2.5L L6 1998–1999 BMW E36 323is - 2.5L L6 1992–1995 BMW E36 325i - 2.5L L6 1992–1995 BMW E36 325is - 2.5L L6 1996–1998 BMW E36 328i - 2.8L L6 1996–1999 BMW E36 328is - 2.8L L6 1995 BMW E36 M3 - 3.0L L6 1996–1999 BMW E36 M3 - 3.2L L6 1999–2000 BMW E36/7/8 Z3 Coupe 2.8L L6 2001–2002 BMW E36/7/8 Z3 Coupe 3.0L L6 1999–2002 BMW E36/7/8 Z3 M Coupe 3.2L L6 1998 BMW E36/7/8 Z3 M Roadster 3.2L L6 1999–2002 BMW E36/7/8 Z3 M Roadster 3.2L L6 1997–1998 BMW E36/7/8 Z3 Roadster 2.8L L6 1999–2000 BMW E36/7/8 Z3 Roadster 2.8L L6 2001–2002 BMW E36/7/8 Z3 Roadster 3.0L L6 All applications require CSF Radiator #7211. ⚠️ Fitment Note — S54 Oil Cooler Lines CSF recommends using European-spec E36 M3 oil cooler lines for S54 swaps. OEM S54 oil cooler lines can also be used but may require minor bending/adjustment to fit properly. The CSF #8241 adapter fitting kit bracket can help secure OEM S54 lines.
