Koyo 3 Row Copper Radiator

[SpeedRacer1]

The single core Koyo replacement for the stock radiator is copper painted black. The only real difference is that it is about 3/4 of an inch thicker than stock. The copper radiator was discontinued a while back and replaced by the much thicker aluminum radiators.

The newer Koyo and fluidyne's are 3 row which should be enough to keep you from overheating. Other things that help are making sure you have the proper water to antifreeze mixture.
