Construction & Design:
The CSF radiator is crafted from 100% high-grade aluminum, TIG-welded to provide exceptional structural integrity and resistance to vibration and thermal stress. The core design incorporates a 2-row, 42mm thick configuration that increases coolant volume and surface area, allowing for more efficient heat transfer. CSF’s proprietary B-Tube technology further enhances thermal conductivity by increasing the contact area between the coolant and the tube walls.
The fins are engineered with a multi-louvered pattern and increased height (5mm) to maximize airflow and heat dissipation without compromising the radiator’s ability to maintain proper engine bay ventilation. CNC-machined mounting brackets ensure exact OEM alignment, preserving factory installation points and maintaining vehicle aesthetics.
Installation & Fitment:
This radiator is designed as a direct replacement for the factory unit on the Toyota GR Supra (2020–2024), BMW Z4 (2019+ with 2.0L or 3.0L engines), and BMW G2X (2019–2021). It installs in the OEM location without requiring any modifications, cutting, or additional fabrication. The plug-and-play design simplifies installation, making it suitable for professional mechanics and experienced enthusiasts alike.
For best results, CSF recommends following the vehicle manufacturer’s repair manual for standard installation procedures. If you are not confident in performing the installation yourself, it is advisable to seek assistance from a qualified automotive technician.
