Mishimoto Automatic Transmission Cooler for 2019-2025 BMW M340i/Z4 and Toyota GR Supra (3.0L)
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Protect your ZF 8HP transmission from performance-robbing heat with the Mishimoto Automatic Transmission Cooler, engineered for select 2019-2025 BMW M340i, Z4, and Toyota GR Supra (3.0L) models. While the factory liquid-to-air cooler provides a baseline for street use, aggressive track days and high-torque B58 builds can quickly push fluid temperatures beyond safe limits. This direct-fit upgrade provides the thermal margin needed to maintain consistent shift quality and transmission longevity.
Our engineering team maximized the available cooling area by expanding the core volume by 162% and increasing the external fin surface area by a massive 412% compared to the stock unit. This cooler utilizes a lightweight aluminum tube-and-fin core equipped with internal cooling fins to extract maximum heat while maintaining proper fluid pressures. Finished in a sleek silver powder coat, this unit installs in the factory location and includes the Mishimoto Lifetime Warranty.
