Built for Boost. Designed for Durability.

Whether you’re daily driving or chasing lap times, heat is the enemy—and the stock radiator isn’t built for long-term abuse. The CSF High Performance Aluminum Radiator is a direct-fit solution for the 2008–2021 WRX and STI, designed to increase cooling efficiency and eliminate common failure points in the factory system.

This radiator features a robust 2-row, 42mm aluminum core and TIG-welded end tanks that ditch the factory plastic. It’s real performance cooling, tested and proven, and now available in your choice of Raw Aluminum or a stealthy Black Finish.
