CSF Cooling - Racing & High Performance Division Engine Oil Cooler - 8240

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.

Note: The CSF #8240 Cooling product is designed for engine swap applications. The product will install in the OEM Location but may require special hoses or connections. If you do not feel confident installing this product CSF recommends taking it to a qualified installation facility.
