Modified cars with higher horsepower produce proportionally more heat, and that can overwhelm a stock cooling system. Upgrade with a high-performance aluminum radiator from Koyo.
Koyo radiators are of all-aluminum construction, with polished end tanks and brazed (not crimped) joints. Each is custom-fit for the application, with all the OEM bungs and fittings.
These radiators do NOT have transmission cooler provisions. If you have an automatic transmission, you MUST have an auxiliary trans cooler to use this radiator.
Fits all 2008-2021 Subaru WRX and WRX STI, and all 2005-2009 Legacy GT/Outback XT.
