Koyo aluminum racing radiators are designed to be direct factory replacement units. Koyo racing radiator features a much thicker core with a more efficient fin design that helps with flow and temperature drop over the surface.

Koyo is Japans largest aftermarket radiator manufacturer, utilizing the latest aircraft quality aluminum and Heli-arc welded. Heli-arc soldering is the highest quality standard for enforcement along aluminum connections. The Koyo radiator is roughly 20mm thicker then stock, allowing for larger capacity, better flow, and faster heat loss over the surface of the core.

Upper radiator hose may require trimming for proper clearance

Great Radiator

Fitment is great but not the easiest to install because it is kind of a tight fit because of the size and the fins are delicate so you must be careful, but doesn't take long! Otherwise awesome product and works great and looks good too!

Check which radiator you have

I purchaced this radiator for my 2002 wrx without double checking that it was a direct oem replacement for my car, apearently late 2002 wrx's had the 2003 radiators put into them with the radiator cap on top. Be sure to check before you buy so you dont have to send it back like I did. Although RSD did a great job with the entire return process and was very helpful.

awesome upgrade awesome shipping came with 6% off on any next orders, due to radiator being about an inch bigger than stock the stock top hose rubbed on belt or fan so had to cut hose back by an inch or so ended up getting samco hoses everything looks and works beautifully !

easy upgrade

Looks great under my Subaru's hood, also got the samco blue hoses. Dresses up the motor very nicely. Slight decrease in running temp and no rise in temp on hot days running hard.
