Evo X MR / Ralliart
The Kozmic SST Transmission AUX Cooler Kit adds additional cooling capacity to the factory SST transmission cooler system while retaining the OEM cooler setup.
This kit is designed to run in series with the OEM cooler system, helping control transmission temperatures during aggressive street driving, track use, and hot weather conditions.
Thoroughly tested with a Dodson heated sump, this setup has proven to provide the required cooling for 20-minute sessions at COTA during Texas summer heat for most Evo X MR and Ralliart applications.
We intentionally keep the cooler core compact to improve SST cooling without unnecessarily blocking airflow to the radiator, intercooler, A/C condenser, or the rest of the vehicle’s cooling system.

Notes
Cooling performance can vary depending on vehicle setup, power level, ambient temperature, driving style, and transmission condition. For maximum performance, this kit pairs well with upgraded SST fluid management components such as the Dodson heated sump.
