CSF Transmission Cooler for Toyota Supra (A90/A91) / BMW M340i / xDrive / M440i / xDrive / Gran Coupe (G-Series) 2020-2025
This high-performance CSF transmission cooler for the Toyota A90 and A91 Supra, along with BMW G-Series models, features an exclusive dual core design that increases core volume by up to 240 percent. The larger oil capacity helps manage heat more effectively, supporting consistent transmission operation during track sessions, drag racing, and aggressive street driving.
During development, CSF worked closely with time attack teams, performance tuners, and race programs to address common issues such as elevated transmission temperatures, gearbox fatigue, and inconsistent shifting under load. The result is a purpose built solution designed to maintain stable temperatures and reliable performance in high stress environments.
This transmission cooler has been proven in real world motorsports applications, including use on the Titan Motorsports A90 Supra drag car, one of the first Supras to achieve an 8 second quarter mile pass. Engineered for a direct fit, this system integrates with the factory front mount heat exchanger and utilizes OEM rubber seals to maintain proper airflow through the cooling stack. The design supports efficient heat exchange without disrupting airflow to other cooling components, making it a reliable upgrade for both street and track focused builds.
