If I go with the N-flow do I have to do any mods to my S5 TII? I know race is just drop in. Is the N-flow the way to go?

 

C'mon people help me out here.

 

I'm pretty sure I remember reading that the N-Flow won't be all that effective with the stock water pump.

Unless you'd like to change the associated water pump config you're better off with the standard race 89-91 model.

 

i got a race koyo for my s5. cheap to order from racing beat and shipped to my house from CA to VA in about 9 days. can't reaslly say how it cools, because my car is down right now.
