Are you upgrading for bling or do you have cooling issues? The Koyo is much heavier than stock. A lot of guys are making 300,400,500hp plus with the stock rad. Since you have EMS you can set the kick-on temp for your fans fyi.

 

Thanks for the advice and also if I want to improve cooling would a Lower Temp Fan Switch & Lower Temp Thermostat help?

 

This thread will show you how to set your fans using EMS:
