Aluminum Radiator, Subaru WRX 2008-2014/Subaru STI 2008-2021

Two-row, 1.65-inch thick brazed aluminum core provides increased coolant capacity — giving the WRX/STI more thermal buffer before temps climb during back-to-back track and rally sessions.
Full aluminum construction with TIG-welded end tanks delivers improved heat dissipation over the stock plastic-tank radiator across the WRX/STI's broad use case.
Two 1.3 bar high-pressure caps, two-way expansion tank cap, one-way radiator cap, and Magnetic Drain Plug included — every component needed for a complete cooling system upgrade.
TIG-welded aluminum end tanks eliminate the stock plastic components that crack under the boost pressure and heat cycles of the EJ engine family.
Two-way expansion tank cap and one-way radiator cap ensure proper flow and system function — preventing overheating under rallycross and autocross duty cycles.
Confirmed direct fit for the Subaru WRX 2008-2014/Subaru STI 2008-2021— no cutting, fabricating, or adapter work required.
Handles the cooling demands of stock and modified WRX/STI builds, including stage-tuned and high-boost setups running street, track, rallycross, and autocross duty.
