After six months of development and testing with some of the best BMW/Supra tuners across the world, CSF is proud to announce its new high-performance all-aluminum charge cooler Front Mount Heat Exchanger upgrade for the A90/91 Toyota Supra (including some BMW G-Series fitment.

Since the vehicle was released in 2019, enthusiasts have been looking for performance upgrades to unleash the full potential of the BMW-sourced B58 engine. It didn’t take long for weak points of the vehicle to become chatter across the internet, in facebook groups, and at race tracks. One of the most apparent problems (and one that was quickly identified by anyone taking the car to a track day): the liquid-cooled charge air cooler system would quickly heat soak 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.
