Everyone knows that heat is the enemy of your automatic transmission. And everyone knows that higher power levels generate more transmission fluid heat. Now you can extend the life of your automatic transmission by installing the new Burger Motorsports High Capacity Trans Cooler kit. This unique plug-and-play kit replaces your factory coolant to trans fluid heat exchanger with a high-capacity fender-mounted air-to-trans fluid radiator. Includes all mounting hardware, lines, and coolant caps required for installation. Installs inside the driverside fender providing ample airflow over the large cooling core via existing openings. The result is dramatically reduced transmission temperature and extended transmission life. This kit is strongly suggested for any BMW E chassis automatic running larger than factory turbos. The thermostat maintains the oil exiting the transmission at the rated minimum temperature in most conditions. Without a thermostat, the transmission fluid coolers are likely to over-cool the fluid, delaying transmission warm-up and performing the critical function of bypassing the cooler until the oil has reached its minimum operating temperature. FEATURES AND BENEFITS Dissipates excess transmission fluid heat Reduces transmission fluid temperature Increases transmission life when racing Increases transmission oil capacity Fitment: 2008-2013 E81 E82 E87 Coupe and Hatchback 135i 2008-2013 E88 Convertible 135i Compatible with both RHD and LHD vehicles. Not compatible with manual transmissions.

The F97 X3M and F98 X4M are powered by the same high-performance S58 engine found in the G8X M3, M4, and M2. While these SUVs deliver impressive power and speed, they also suffer from the same heat management challenges as their sedan and coupe counterparts. That’s where CSF’s advanced cooling solutions come in—becoming essential upgrades for S58 owners, even for those keeping their engines mostly stock. After over a year of development and testing, CSF is proud to introduce the Front Mount Heat Exchanger & Transmission Cooler Module for the F9X X3M and X4M. One of the biggest challenges in developing a Front Mount Heat Exchanger for these models was limited space. Unlike the G8X models, the X3M and X4M feature a different transmission oil cooler, restricting the available room for a larger heat exchanger due to the mounting cradle. After extensive testing with smaller core designs, CSF determined that integrating the Heat Exchanger with a Transmission Cooler Upgrade was the optimal solution for maximizing both size and performance. By combining both components into a single cooling module, CSF achieved a design that accommodates the same core size as the G8X Heat Exchanger. The integrated Auto Transmission Cooler utilizes the same dual-core design as the G8X Transmission Cooler and is seamlessly fitted to the new Heat Exchanger. This innovative all-in-one module not only addresses two major cooling issues for the X3M and X4M but also reduces overall costs—savings that are passed along to the customer. Compared to the stock heat exchanger, CSF’s upgraded design offers significant improvements. The TIG-welded aluminum tanks are much larger than the OE plastic tanks, providing superior strength and fluid volume. A 2-row 42mm core increases cooling efficiency and capacity, utilizing CSF’s Exclusive B-Tube Technology to enhance airflow and heat dissipation. Multi-louvered fins further expand the heat exchange surface area, improving overall cooling performance while maintaining proper airflow. Built entirely from high-strength aluminum, this system ensures maximum durability and reliability. The mounting tabs and brackets are significantly stronger than the factory plastic components, offering improved longevity. Additionally, the heat exchanger includes an integrated bolt-on metal rock guard, which is far more robust than the stock plastic version—providing better protection against road debris and ensuring greater confidence in the system’s resilience. CSF’s Transmission Cooler features an innovative dual-pass design that dramatically enhances cooling performance. Unlike the OEM single-core cooler, CSF’s front-to-back stacked core design more than doubles the surface area and nearly triples the core volume. Engineers leveraged the extra space freed up by replacing the OE cooler and oversized plastic cradle, effectively doubling cooling capacity while maintaining a perfect OEM fit—no modifications required. By switching from a single-core to a dual-core design, CSF achieved a 201% increase in overall volume, significantly improving heat dissipation and fluid capacity. Using CSF’s AC Condenser Technology, the cooler incorporates a high-pressure 1-row 16mm 9-channel microtube design, optimizing oil flow and maximizing surface area contact. These features work together to provide the most effective heat dissipation possible, keeping transmission temperatures under control even under extreme conditions. With CSF’s new Front Mount Heat Exchanger & Transmission Cooler Module, X3M and X4M owners can enjoy superior cooling efficiency, enhanced durability, and long-term performance—all in a cost-effective, OEM-fit package.
