I am building a S5 Turbo and want to do the cooling right from the start. I am curious about the difference between the Corksport and the N-Flow from Koyo. Corksport is 60mm and the N-flow is only 53mm but the N-flow is three-pass. Does it make much difference on our cars? My build will be heading to about 350hp and I do have a front mount intercooler, so there is a little blockage there. What do you all know about this?

 

The Nflow offers much better cooling with the FMIC in place. Ive owned them both and the NFlow is roughly 20 more efficient at cooling than the standard single pass at a stand still with factory fan in place. You can get the NFlow for nearly the same price with some research, and added bonus for being able to switch to a electric fan!

 

Godspeed
