# CSF 2020 Toyota GR Supra (A90) Heat Exchanger

CSF's B58 high-performance heat exchanger will be a critical component to keeping your Supra/BMW's charge air cool, and out of limp mode. The upgraded heat exchanger is especially important when upgrading turbos and/or running performance tuning software. The original 2nd Gen B58 heat exchanger is a 1-row unit that is 25mm thick. In comparison, CSF has used its industry-exclusive world's largest 2-row core (68mm) with CSF's B-Tube technology. A unique tank design allows the larger CSF core to still fit into the OEM cooling system housing. The CSF improved design, includes billet transmission cooler mounts, and metal rock guard with improved airflow characteristics. CSF is the only company to include a rock guard and incorporate OEM transmission cooler mounting points for a true plug-and-play "drop-in" fit.
