Upgrade your cars performance with the do88 Performance Transmission Cooler!
Background
Designed specifically for BMW M340i/Z4 and Toyota GR Supra, the do88 Automatic Transmission Cooler ensures smooth and efficient shifting. While the latest Supra / M340i / Z4 lacks the manual gearbox, the swift ZF 8HP transmission coupled with the B58 compensates impressively. Yet, like all sports cars, heat remains a significant challenge, especially in tuned cars that generate more heat during rigorous street, track, or drag strip driving.
Our solution
The 2019+ BMW M340i/Z4 and GR Supra models come with an external liquid-to-air transmission cooler. However, for tuned cars, the generated heat can often exceed the OE coolers capacity. Recognizing this, our engineers redesigned the transmission coolers core, increasing its volume by 184% and the cooling surface area by 176% while maintaining similar fluid pressures. We upgraded the tubes with harmonica tubes with internal channels, ensuring optimal cooling efficiency. Whether youre spending a day on the track or enjoying a drive through the backroads, the do88 Transmission Cooler helps keeping the temperatures in check.
Installation
Installing the much larger do88 Performance Transmission Cooler is hassle-free, requiring no modifications (see installation instructions).
