BMW Transmission Oil Cooler - do88 OC-190
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 cooler's capacity. Recognizing this, our engineers redesigned the transmission cooler's 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 you're 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).

do88.se is an online Swedish vendor hosted and governed by do88 AB. do88 is based in Nykvarn, outside Stockholm, and was founded in 2007. Our business started with universal silicone hoses, and has since grown to become one of the largest silicone hose distributors in the northern hemisphere. We keep everything in stock and ship worldwide. Being Swedes, we started focusing on SAAB and Volvo, which led us to develop our own model-specific parts that go beyond just hoses. Our expertise now extends to intercoolers, oil coolers, radiators, intake systems, and much more, for a variety of car brands and models. All products are developed in-house and sold based on our criteria. Our commitment to proven performance, high quality, and excellent customer support has established do88 as a respected name in the auto parts industry. We also offer related products including plastic connections, aluminum piping, hose clamps, heat protection, and BOVs from GFB, as well as air filters from BMC and intercooler cores from industry titan Garrett. Our goal is to be the clear choice for automotive and industrial cooling needs.
