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

BMW S54 Swap E36 Race-Spec Dual-Pass Oil Cooler 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. Unique Top/Bottom Dual-Pass Design for Maximum Surface Area and Flow Fully TIG-Welded Extruded End Tank Design for Superior Reliability & Durability Turbulated Heavy-Duty Bar/Plate Design for the Most Reliable & Durable Oil Cooler Available 8 Rows of Maximum Cooling with a High Density Multi-Louvered Fin Pitch Design Designed to Work with CSF's S54 Swap All-Aluminum Radiator (CSF #7211)
