CSF is the world leader in cooling technology. From its experience starting with the transmission in the BMW F8X M3, M4, and M2 Comp, CSF applied several different features exclusive to its manufacturing technologies. An innovative dual-core design allows for a 240% increase in core volume, resulting in maximum performance and maintaining optimal shifting during extreme racing conditions – from road racing to the drag strip. During R&D, CSF consulted with a network of partners, including leading time attack teams, tuners, and more. Often, the feedback was gearbox fatigue and sluggish shifting with transmission temperatures overheating under prolonged or hard use. CSF has the answer with our industry-leading transmission cooler for the A90/91 Supra and BMW G-Series. Installed in one of the world’s fastest A90 Supra – Titan Motorsports Drag Race Supra (first Supra to reach 8s in the 1/4 mile).
CSF’s industry-exclusive dual-core design allows for maximum performance and the largest core volume oil capacity without affecting airflow into the rest of the cooling system. No more transmission temperature overheating or expansion tank overflow during racing conditions. Designed as a drop-in fit to work with both the OEM Front Mount Heat Exchanger as well as CSF’s High-Performance version (CSF #8154) with included rock guard. Also designed to utilize the OEM top/bottom rubber seals for optimal airflow into the cooling system.
