CSF's B58 heat exchanger is a critical component to keeping Supra/BMW charge air cool and out of limp mode. The upgraded heat exchanger is especially important when upgrading turbos. The original 2nd Gen B58 heat exchanger is a 1-row, 25 mm thick. For comparison, CSF has used the world's largest 2-row cell (68 mm) with CSF's B-Tube technology.

The unique reservoir design allows the larger CSF core to still fit into the OEM cooling system housing. The improved CSF design includes billet radiator mounts and a metal rock guard with improved airflow characteristics.
