CSF BMW Oil Cooler -10AN Adapter Fitting Kit | 8241

The CSF 8241 adapter fitting kit allows custom oil lines with -10AN female fittings to connect to compatible CSF 8032 and 8240 oil coolers. It also fits the S54 engine-side flange, giving BMW swap builders an option for configuring AN oil lines instead of relying on factory pipe routing. Ships fast across Canada and the US.

Plan the complete conversion: CSF specifies a quantity of two 8241 kits for a complete AN line conversion using the cooler-side and S54 engine-side connections. One kit is not a complete engine-to-cooler hose package. Confirm the cooler, engine-side flange and hose-end clearance before ordering; this is not a universal adapter for every BMW oil cooler.

Specifications and Compatibility

  • Brand: CSF.
  • Manufacturer part number: 8241.
  • Accepts -10AN female oil-line fittings.
  • Compatible oil coolers: CSF 8032 and CSF 8240.
  • Also fits the S54 engine-side flange.
  • Bracket construction: CNC-machined billet aluminum.
  • Ordering quantity: one adapter kit; two kits required for a complete AN line conversion as specified by CSF.

Application Notes

Select this kit by the exact oil cooler and flange configuration rather than vehicle model alone. Its compatibility with the CSF 8032 and 8240 does not establish compatibility with other factory or aftermarket coolers.

CSF also notes that the 8241 kit's bracket can be used to secure OEM S54 oil cooler lines in the 8240 swap installation. Follow CSF's guidance for that arrangement, since factory S54 lines may require bending and adjustment.

What You Are Ordering

This listing is for one CSF 8241 adapter fitting kit. The oil cooler, custom hoses, female hose-end fittings and other conversion components are separate items. An exact seal and fastener inventory is not listed here; confirm the supplied components against CSF's current instructions before assembly.

Installation Notes

Have an experienced installer verify port alignment, fitting engagement and hose routing for the complete oil circuit. Use the specified seals and fastening procedures, keep all oil passages clean, and prevent hose strain or contact with hot or moving components.

Check the oil level and inspect all connections for leaks before driving. Do not assume an AN adapter alone provides a thermostat, changes oil pressure or increases cooling performance.
