The PLM Performance Aluminum Radiator is designed for the 2022+ Subaru WRX (VB platform) to deliver significantly better cooling than the factory unit, especially under demanding conditions like track days or turbo upgrades. Built from fully TIG-welded aluminum with a robust 42 mm dual-row core, this direct-fit radiator boosts coolant capacity by over one gallon and provides superior heat dissipation, all while retaining an easy, no-modification installation.
