CSF Cooling High-Performance Transmission Oil Cooler 2021+ BMW M3/M4

CSF Cooling has developed a High-Performance Transmission oil cooler for the 2021+ BMW M3/M4, designed to allow the cooling system to keep up on modified/tuned vehicles, especially track and competition cars. Transmission oil temperatures have a major impact on the shifting performance of the automatic transmission. These rising fluid temperatures cause delays in shifting. While sluggish shifting is frustrating, the larger concern is the possible damage that occurs with higher temperatures. 

Upgrading to CSF Cooling's dual-core design increases overall volume by 194%. This design offers improvements in heat dissipation and increases the fluid capacity of the coolers by approximately 94%. Utilizing its AC Condenser Technology, a 1-Row Super-High Pressure 16mm 9-Channel Microtube design optimizes oil flow and offers maximum surface area contact. These features combine to yield the best possible heat dissipation from the system.
