Koyo Aluminum Radiator 2003-2007 WRX and STI

  • 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 2003-2007 Subaru WRX and WRX STI. Can be fit to 2002 WRX if you plumb the overflow tube in the 2003+ style.
