Built for Track Days, Tuned for Daily Life
When you're pushing your Subaru to the edge—cooling isn't just important, it’s critical. The CSF Competition Race-Spec Aluminum Radiator is built from the ground up for drivers who demand high performance and zero compromise.
This isn’t your average radiator. Unlike factory units with plastic end tanks and thin cores that fatigue over time, this radiator features an all-aluminum, TIG-welded design with CSF’s 42mm 2-row race-spec core. It’s engineered to deliver consistent, efficient cooling under extreme conditions—whether you're sliding through hairpins or crawling through traffic.
This radiator is designed for direct fitment using factory mounting points and hoses. It’s a bolt-in solution that works with OEM or aftermarket cooling fans. No trimming. No drama.
