do88 Transmission Cooler BMW G-Series & Supra A90
Enhance your car’s performance with the do88 Performance Transmission Cooler!
Tailored specifically for BMW M340i/Z4 and Toyota GR Supra models, the do88 Automatic Transmission Cooler guarantees seamless and efficient shifting. Despite the absence of a manual gearbox in the latest Supra/M340i/Z4 models, the swift ZF 8HP transmission combined with the B58 engine compensates impressively. However, heat management remains a significant challenge for all sports cars, particularly tuned vehicles that generate increased heat during demanding street, track, or drag strip driving.
Our Solution
The 2019+ BMW M340i/Z4 and GR Supra models are equipped with an external liquid-to-air transmission cooler as standard. Nevertheless, for tuned cars, the heat produced can often surpass the capacity of the original equipment (OE) cooler. Acknowledging this, our engineers re-engineered the transmission cooler’s core, enhancing its volume by 184% and the cooling surface area by 176%, all while maintaining similar fluid pressures. We upgraded the tubes with harmonica tubes featuring internal channels, ensuring optimal cooling efficiency. Whether you’re spending a day on the track or enjoying a drive through winding backroads, the do88 Transmission Cooler helps to keep temperatures under control.
Key Features
- Core volume increased by 184% and the active cooling area by 176% compared to the original cooler (OE).
- Harmonica tubes ensure optimal oil flow and maximum surface area contact.
- Compatible with the do88 Front Intercooler Radiator (WC-400).
