CSF BMW Z4/Toyota Supra High Performance Aux Cooler (G29/A90)
Description
When it comes to high-performance cooling, don’t settle for aftermarket options that reuse the OEM plastic rock guard. The OEM rock guard is designed for the original radiator core and can block airflow when paired with aftermarket radiators, reducing cooling efficiency. CSF went beyond industry norms, redesigning its included detachable aluminium rock guard to maximize airflow while providing excellent protection against rocks and debris. Proven in CSF’s in-house wind tunnel, this upgraded design ensures optimal cooling performance without compromise.
The CSF Auxiliary Radiator fits seamlessly on both the left and right sides of the vehicle with a true plug-and-play installation. Featuring CNC-machined mounting brackets and OEM-style “Quick Connect” connections, it requires no modifications—even when used with aftermarket aero upgrades.
