CSF BMW G8X M3/M4 High-Performance Radiator Front Mount Heat Exchanger
£804.00
The CSF Heat Exchanger is engineered for superior cooling efficiency, featuring a 2-row, 42mm-thick core with CSF’s exclusive B-Tube Technology, offering a significant upgrade over the standard OEM single-row design. By increasing the core size and end tanks, this system enhances overall volume, allowing for better heat absorption. The high-efficiency core not only dissipates more heat but also improves airflow to the radiator positioned behind the heat exchanger.
For ZF8 Automatic Transmission vehicles, this heat exchanger has been developed alongside CSF’s Race-Spec Dual Core Transmission Oil Cooler (CSF #8221) for optimal performance. Included in the kit are two Black Rock Guards, providing full protection above and below the crash bar—especially useful when paired with aftermarket open-face race-style grilles, which are popular for both performance and aesthetics. Keeping your heat exchanger safeguarded from debris is essential for longevity and efficiency.
Backed by over 100 hours of track testing and thousands of miles of real-world driving, the CSF High-Performance Front Mount Heat Exchanger is fully tested, proven, and ready to enhance your vehicle’s cooling system.

If you have any doubt on this approval, please contact us immediately for confirmation.
