CSF BMW M3 / M4 G8x Transmission Cooler

CSF stone shield gearbox for BMW M3 / M4 G8x. Although the OEM gearbox radiator is suitable for the G8X in the factory state, it begins to be somewhat inadequate in modified/tuned vehicles. In particular, those that are intensively used on track/professionals. The temperature of the gear oil has a big impact on the efficiency of the gear shift in the automatic gearbox. If the fluid reaches optimal temperature, you will start to notice some delays in the gear shift. Slow change of gear can be quite frustrating, but the real problem is the damage that can be caused when the temperature becomes too high. By changing the design from a single OEM core to a dual core, CSF was able to increase the overall volume by 194%. This design provides a radical improvement in heat removal and increases the radiator capacity by ~94%. Using CSF AC condenser technology, a 1-row, 9-channel 16 mm diameter microtube with very high pressure optimizes oil flow and provides maximum contact area. The combination of these features provides the best possible heat discharge from the system.
