CSF 20+ Toyota GR Supra High-Performance DCT Transmission Oil Cooler - 8183

CSF is the world leader in cooling technology. From its experience starting with the transmission in the BMW F8X M3, M4, and M2 Comp, CSF applied several different features exclusive to its manufacturing technologies. An innovative dual-core design allows for a 240% increase in core volume, resulting in maximum performance and maintaining optimal shifting during extreme racing conditions - from road racing to the drag strip. During R&D, CSF consulted with a network of partners, including leading time attack teams, tuners, and more. Often, the feedback was gearbox fatigue and sluggish shifting with transmission temperatures overheating under prolonged or hard use. CSF has the answer with our industry-leading transmission cooler for the A90/91 Supra and BMW G-Series. Installed in one of the world's fastest A90 Supra - Titan Motorsports Drag Race Supra (first Supra to reach 8s in the 1/4 mile).

CSF's industry-exclusive dual-core design allows for maximum performance and the largest core volume oil capacity without affecting airflow into the rest of the cooling system. No more transmission temperature overheating or expansion tank overflow during racing conditions. Designed as a drop-in fit to work with both the OEM Front Mount Heat Exchanger as well as CSF's High-Performance version (CSF #8154) with included rock guard. Also designed to utilize the OEM top/bottom rubber seals for optimal airflow into the cooling system.

Product Details

CSF is the world leader in cooling technology. From our experience starting with the transmission in the BMW F8X M3, M4, and M2 Comp, CSF applied several different features exclusive to its manufacturing technologies.

During R&D, CSF consulted with a network of partners, including leading time attack teams, tuners, and more. Often, the feedback was gearbox fatigue and sluggish shifting with transmission temperatures overheating under prolonged or hard use.

CSF has the answer with our industry-leading transmission cooler for A90/91 Supra and BMW G-Series. Installed in most of the world's fastest A90 Supras & G-Series, including Titan Motorsports Drag Race Supra which was the first to reach the 8s in the 1/4 mile.

Design & Engineering

While the OEM Transmission Cooler is adequate for the A90/G-Series in stock form, it starts to come up short on modified/tuned vehicles. Specifically ones that see heavy track/competition use. Transmission oil temperatures have a major impact on the shifting performance of your automatic transmission.

If the fluid passes optimal temperatures you will start to see some delays in shifting. Sluggish shifting can be quite frustrating. However, the real concern is the damage that can be done to the transmission when temperatures get too high. There are often cases where drivers don't notice the change in shifting performance due to the gradual onset, but the damage is still being done slowly on a very expensive and important component.

Dual-Core Advantage

By changing from the OEM single core design to a dual core, CSF was able to increase the overall volume by 240%. This design offers a drastic improvement in heat dissipation and increases the fluid capacity of the coolers by 130%. Utilizing CSF's AC Condenser Technology, a 1-Row Super-High Pressure 16mm 9-Channel Microtube design optimizes oil flow and offers maximum surface area contact. These features combine to offer the best possible heat dissipation from the system.

OEM vs CSF

CSF's industry-exclusive dual-core design allows for maximum performance and the largest core volume oil capacity without affecting airflow into the rest of the cooling system. No more transmission temperature overheating or expansion tank overflow during racing conditions.

Plug and Play Installation

CSF's High-Performance transmission Cooler installed. Designed as a drop-in fit to work with both the OEM Front Mount Heat Exchanger as well as CSF's High-Performance version (CSF #8154) with included rock guard. Also designed to utilize the OEM top/bottom rubber seals for optimal airflow into the cooling system.

⚠ Fitment Notes

The CSF #8183 will NOT fit the late production 2024 or 2025+ BMW G2X M340i or M440i models equipped with the B58N. Production of the B58D ended in 07/2024 for the M340i and 03/2024 for the M440i.

BMW updated the part number for the Transmission Oil Cooler for the 2025 model. 2020-2024 models use the OE 17219494828, but the 2025+ uses the OE 17218852263.
