CSF Oil Coolers

Any who has ever tracked an E46 M3 or even just driven one hard knows how quickly the oil temperatures can climb. For the E46 M3, CSF developed the Dual Pass Race Spec Oil Cooler (CSF #8032) with Rogue Engineering. This has been the go to solution for the E46 M3 community and will work on S54 Swaps when paired with this radiator. Why are there two oil coolers then you might ask? Because of the chassis differences, the CSF #8032 will not allow owners to retain air conditioning with their S54 Swap. Enter the new CSF S54 Swap Race Spec Oil Cooler. This new oil cooler is shorter on the right hand side allowing owners to run the A/C lines in the OEM path. Even though the #8240 is slightly smaller than the #8032, you can expect similar performance levels as they both feature a dual pass design with 8 cooling rows and are the same turbulated heavy-duty bar/plate construction. Both oil coolers utilize the S54 OEM oil line connections. However, CSF will be offering a fitting kit with -10 AN hookups for customers looking to run custom oil lines. This fitting kit should be available by the second quarter of 2023. BMW S54 Swap E36 Race-Spec Dual-Pass Oil Cooler.
