CSF Racing Aluminum Radiator 2018-2023 Crosstrek / 2017-2022 Impreza

The stout 2.0L (FB20) and 2.5L (FB25) engines in the Crosstrek and Impreza handle off-roading well, but added stress from traction loss, steep climbs, and extra gear can push engine temperatures beyond what the factory radiator can manage. That’s where the CSF High-Performance All-Aluminum Radiator comes in.

Featuring a 42mm 2-row aluminum core with CSF’s exclusive B-Tube Technology, this radiator boosts cooling capacity and improves heat dissipation by up to 15%. Multi-louvered fins maximize airflow—crucial for off-road driving where speeds are low and airflow relies heavily on fans. A larger, more efficient core also helps when the radiator is coated in dust or mud.

Durable TIG-welded aluminum end tanks eliminate the weak points of factory plastic tanks, ensuring strength and reliability. Designed as a true plug-and-play upgrade, this radiator installs easily with no cutting or modifications required.
