This aftermarket replacement radiator from CSF isn't fancy, but it's our least expensive one and it gets the job done. Plastic end tanks are light; although they won't last forever, did we mention how inexpensive it is?
Note: This radiator includes provisions for an automatic transmission cooling circuit. If your car has a manual transmission (and if you are on this site, you probably do), you can just ignore those fittings.
Note 2: The radiator comes without a radiator cap If you need a new one we suggest the OEM Subaru round cap.
Fits all 2008-2014 manual-transmission Subaru WRX and 2008-2020 WRX STI, plus manual-transmission 2005-2009 Legacy GT/Outback XT.
