CSF 8258 Auxiliary Cooling Radiator for BMW M2 (F87) / M3 (F80) / M4 (F82 / F83)

CSF 8258 Auxiliary Radiator for BMW M2 (F87) / M3 (F80) / M4 (F82 / F83)

CSF has engineered these radiators for simple installation. Each radiator fits into the factory location and utilizes the factory quick-connect fittings. The high-performance auxiliary radiators work in conjunction with the rest of the cooling system to reduce temperatures. They not only help keep temperatures within optimal limits but also extend the heat soak threshold. There is nothing worse than having to cut a track session short due to needing to do cool-down laps.

Each CSF F8X auxiliary radiator can be installed on either the driver or passenger side. The fittings and end caps can be swapped and easily configured for either side.

Compared to the OEM F8X radiators, the CSF units are a significant upgrade. CSF has eliminated the factory plastic mounting shroud by integrating it into a modular design that fits both sides. This improved design allows for an increase in the size of both the core and the end tanks. The extra space freed up from the mounting block allowed for a ~7% increase in core size and a ~10% increase in end tank volume. By utilizing a larger, dual-core 42mm unit, cooling efficiency and performance are significantly increased. The high-efficiency core, using CSF's exclusive B-Tube technology, maximizes airflow and heat dissipation. The all-aluminum construction ensures optimal performance and durability. The mounting pins and brackets are far more robust and durable than the factory plastic mounting system. Additionally, the black finish provides added protection and allows for a stealthy installation behind your F8X's grille.

Furthermore, the CSF auxiliary radiators feature integrated bolt-on guards to protect the radiators. You have undoubtedly heard the horror stories of OEM radiators getting punctured and spewing fluid all over the road or track. You can now rest assured that your cooling system is well-protected from road debris.

CSF has utilized a modular design, allowing the auxiliary radiator to be installed on either side. This design has a number of benefits. One of these benefits is for serious track use. Having spare parts on hand is always a good idea. Having one auxiliary radiator that fits both sides, where typically two are needed, saves significant cost and space. Purchasing an auxiliary radiator as a spare is more cost-effective and space-efficient for CSF applications.
