GrimmSpeed Ultimate Cooling Bundle | 2015-2021 Subaru WRX (GRM.1294.5K)

Ultimate Cooling Bundle for 2015-2021 Subaru WRX by GrimmSpeed

Heat is the enemy of power and reliability—especially on the FA20 platform. That’s why we built this bundle to go after the issue head-on. By combining our GrimmSpeed Front Mount Intercooler Kit with the ultra-capable CSF 42mm Race-Spec Radiator, we’re giving WRX owners a complete cooling solution that works from every angle.

Subaru’s FA20 engine is notorious for heat management challenges—especially when power increases. This kit takes those concerns off the table. Our FMIC handles intake charge temps and eliminates heat soak, while the CSF radiator improves coolant efficiency with a thicker, dual-row all-aluminum core. The result? Cooler engine temps, more stable performance under load, and a WRX that’s ready to go lap after lap—or commute after commute.
