Choose options
Upgrade your cooling system with the CSF 2-Row 42mm Auxiliary Radiator – a high-performance, drop-in replacement for the OEM units. Designed to fit both the left and right sides without any modifications, this radiator features CNC-machined brackets and OEM-style quick-connect fittings for a true plug-and-play installation.
Unlike other options that reuse the OEM rock guard—reducing airflow—CSF includes a custom-designed rock guard to maximize cooling efficiency while protecting against road debris. Proven through in-house wind tunnel testing, this radiator ensures optimal airflow and performance.
Compatible with:
Toyota Supra A90 / BMW M240i G42 / M340i G20 / Z4 G29 (B58)
Note: Two radiators are required for full vehicle replacement (left and right). Add 2 to cart to replace both sides. BMW M240i G42 requires only 1.
