A90 Supra / BMW G-Series High-Performance Heat Exchanger w/ Rock Guard

One of the most apparent problems for the 2nd gen B58 Motor is the liquid-cooled charge air cooler system quickly heat soaks with no ability to recover. This would cause the intake air temperatures (IATs) to spike, resulting in the ECU cutting the power output of the vehicle, and eventually putting the car into limp mode. CSF engineers witnessed the overheating issue first-hand as they were in attendance at the Global Time Attack Finals at Buttonwillow Raceway in November 2019. Several new heavily modified Supra racecars could barely go two or three laps in moderate ambient conditions without having the car go into limp mode, forcing drivers to take a cool down lap (or two), with some even coming into the pits to have their front mount heat exchangers sprayed down with cold water.

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.
