Description

Description
Improve your car's performance with the do88 Performance Transmission Cooler!

Context

Designed specifically for the BMW M340i/Z4 and Toyota GR Supra, the do88 Automatic Transmission Cooler ensures smooth and efficient gear changes. Although the latest Supra/M340i/Z4 doesn't come with a manual transmission, the fast ZF 8HP transmission paired with the B58 cooler impressively compensates. However, as with all sports cars, heat remains a major challenge, especially in modified vehicles that generate more heat during rigorous driving in the city, on the track, or in drag racing.

Our Solution

The 2019+ BMW M340i/Z4 and GR Supra models come equipped with an external liquid-to-air transmission cooler. However, for modified cars, the heat generated can often exceed the capacity of the OE cooler. Recognizing this, our engineers redesigned the transmission cooler's radiator core, increasing its volume by 184% and its cooling surface area by 176% while maintaining similar fluid pressures. We improved the tubing with harmonic tubes featuring internal channels, ensuring optimal cooling efficiency. Whether you're spending a day at the track or enjoying a drive on back roads, the do88 Transmission Cooler helps keep temperatures under control.

Installation

The installation of the significantly larger do88 Performance Transmission Cooler is hassle-free, requiring no modifications (see installation instructions).

Key Features:

Radiator core volume increased by 184% and active cooling area by 176% compared to the original (OE) cooler.
Harmonica tubes ensure optimal oil flow and maximum contact with the surface.
Compatible with the do88 Front Intercooler Radiator (WC-400).
