Improve the performance of your 2021+ BMW G8X M2/M3/M4 with the do88 transmission cooler, a cooler designed for optimal transmission temperatures under demanding driving conditions!
Background
For the 2021+ BMW G8X M2/M3/M4 models, the ZF 8HP automatic transmission is robust and fast, designed to handle the high power of the S58 engine. However, upgrading the engine with additional performance components and tuning can overload the original cooling system, especially during track driving. The risks of transmission overheating include slower shifting and the possibility of transmission damage. To address this temperature challenge, do88 has developed an upgraded transmission cooler to help maintain proper temperatures and keep the transmission operating properly.
Our Solution
The do88 high-performance transmission cooler for the 2021+ BMW G8X models significantly improves cooling efficiency. Our engineers redesigned the transmission cooler core, increasing its volume by 71% and its cooling surface area by 50%, while maintaining similar oil pressures. We upgraded the tubes to spring tubes with internal channels, ensuring optimal cooling efficiency. This also increases the system’s cooling capacity with a 42% increase (8.5 dl versus 6 dl) in oil volume. The do88 cooler uses a dual-pass design, meaning the fluid remains in the cooler for longer, ensuring greater heat dissipation.
Installation
Installation of the significantly larger do88 Performance transmission cooler is simple and requires no modifications (see installation instructions).
Key Features
The core volume is increased by 71% and the active cooling area by 50% compared to the original equipment (OE) cooler.
Spring tubes ensure optimal oil flow and maximum contact surface area.
OEM-style “Quick Connect” input/output connections.
Perfect fit, eliminating the need for modifications.
