Fits select 2020-2025 Toyota GR Supra and BMW M240i, M340i, M440i, and Z4 M40i models. This high-performance DCT transmission oil cooler is engineered to eliminate gearbox fatigue and sluggish shifting caused by overheating during track use, time attack, or high-output street driving.

Using an industry-exclusive dual-core design, CSF has engineered a drop-in cooling solution that provides a 240% increase in core volume over the factory unit. By stacking two 16mm cores for a total width of 32mm, this cooler significantly increases thermal mass and heat dissipation without blocking airflow to the rest of the cooling stack. The design utilizes CSF’s AC condenser technology, featuring a 1-row super-high pressure 9-channel microtube for maximum oil flow and surface area contact.
