CSF BMW F8X M3/M4/M2C Auxiliary Radiators with Rock Guards - Fits 2015-2021 M2/M3/M4 Models

This component is designed to significantly improve the efficiency and reliability of your vehicle's cooling system. By eliminating the original equipment plastic mounting pod, this design incorporates a modular approach that enhances both the core size and tank volume. The result is a 7% increase in core size and a 10% increase in tank volume, contributing to a marked enhancement in cooling capacity.

Utilizing a larger 2-row 42mm core along with exclusive B-Tube Technology, airflow and heat dissipation are optimized, ensuring that temperatures remain under control even during intense driving conditions. Constructed entirely of aluminum, this component provides superior durability compared to OEM parts, while the strengthened mounting pins and brackets offer greater reliability than the standard plastic systems.

Additionally, the black finish not only enhances aesthetics but also serves as an extra layer of protection against the elements. Equipped with integrated bolt-on rock guards, this part ensures that the cooler remains safeguarded from road debris, mitigating the risk of punctures that could lead to fluid loss.
