The BMW M4 Auxiliary Radiator - Left or Right - CSF - All-Aluminum, 2-Row 42mm B-Tube Core with Rock Guards - Satin Black, is an essential upgrade for your 2015-2020 BMW M4. Engineered for enhanced performance and longevity, it replaces your original equipment with a robust option designed to withstand high demand and vigorous driving conditions.

This high-performance auxiliary radiator offers a superior cooling solution compared to the OEM coolers. The CSF design has improved on the original by eliminating the OE plastic mounting pod, integrating it into a more efficient modular design for both sides. Thanks to a larger 2-row 42mm core and a core size increase of 7%, along with a 10% greater tank volume, the cooling efficiency is significantly heightened. CSF's exclusive B-Tube Technology ensures maximized airflow and heat dissipation, helping to maintain optimal temperature ranges while prolonging the heat soak threshold. The product is built entirely from aluminum, providing exceptional durability and performance, with each radiator mounted securely in the OEM location using quick connections.
