CSF BMW E36 S54 Swap Race-Spec Dual-Pass Oil Cooler | 8240

The CSF 8240 Race-Spec oil cooler is designed for BMW E36 S54 engine swaps using the CSF 7211 swap radiator. Its shortened right-hand side provides clearance for A/C lines following their OEM routing, helping builders retain air conditioning without using the larger 8032 cooler layout. Ships fast across Canada and the US.

Swap-specific fitment: This is not a universal bolt-in oil cooler for every S54-powered BMW. Verify the radiator, mounting arrangement, A/C routing and oil-line connections before ordering. CSF designed 8240 around E36 M3 Euro-spec oil cooler lines; factory S54 lines may require bending and adjustment. The separate CSF 8241 adapter kit is needed for -10AN connections.

Specifications and Features

  • Manufacturer part number: CSF 8240.
  • Application: BMW E36 S54 engine-swap cooling configurations.
  • Designed to work with CSF 7211 S54-swap all-aluminum radiator.
  • Eight-row, top/bottom dual-pass design.
  • Turbulated heavy-duty bar-and-plate construction.
  • High-density multi-louvered fin design.
  • Fully TIG-welded extruded end tanks.
  • Motorsport Silver finish.
  • Shortened right-hand layout for A/C line clearance.

Oil-Line Compatibility

CSF recommends E36 M3 Euro-spec oil cooler lines, BMW part number 17212227235. The 8240 connection spacing is 41.4mm center-to-center, unlike the 37.5mm spacing associated with the S54 OEM connections on CSF 8032.

E46 M3 S54 oil cooler lines, BMW part number 17222283209, may be used with minor bending and adjustment as directed by CSF. The bracket from the CSF 8241 adapter kit can also be used to secure the OEM S54 lines. Confirm the complete arrangement with your installer rather than assuming an unchanged direct connection.

Ordering and Installation

This listing is for the 8240 oil cooler. The CSF 7211 radiator, 8241 -10AN fitting adapter kit, oil lines and other swap components are separate items unless explicitly supplied with your order. It is not a complete S54 swap cooling package.

Have an experienced BMW swap installer check mounting clearance, hose routing and fitting compatibility, then follow CSF's current installation instructions. Keep oil passages clean during assembly, use the correct sealing components and fastener procedures, and verify oil level and leak-free operation before driving.

No fixed oil-temperature reduction, power increase or universal track-performance guarantee is claimed. Actual cooling depends on airflow, installation and operating conditions.
