CSF is pleased to announce the new high performance CSF auxiliary radiators for the BMW G8X M3/ M4/ M2.
Cooling systems for BMW
CSF, a recognized leader in cooling systems for BMW, has introduced a new product for the G8X (M3/ M4/ M2) series - high-performance auxiliary radiators. The new product complements the popular Power Cooling Package series, which has already gained success among enthusiasts and motorsport teams.
Advantages of CSF radiators over OEM versions
CSF radiators are far superior to standard OEM versions. Their TIG-welded aluminum construction provides:
- Increased strength due to larger dimensions compared to plastic OEM radiators
- Improved cooling efficiency thanks to a 42mm thick 2-row core with exclusive CSF B-Tube technology and 5mm fins that optimize heat dissipation
- Radiators help maintain optimal temperatures even during aggressive driving, increasing the heat soak threshold and allowing for longer performance

| Main rows | 2-row | 1-row |
| Fin height | 5 mm | 5 mm |

BMW S58 engine cooling :
For S58 engines, which often exceed 1000 horsepower, standard radiators become the weak link in extreme conditions, which can lead to overheating and limp mode. With the new CSF radiators, this is no longer a problem - the cooling system ensures stable engine operation even under maximum load.
This new product will be a great choice for track racing, motorsports or drivers looking for maximum reliability and performance from their G8X.
