Ok, so I am trying to figure out the best radiator for my s13, I decide to go with Koyo since they have some decent prices. I keep on seeing a bunch of different prices for what looks like the same radiator, and there is also an N-Flow model, but im not entirely sure how to tell the difference, or which one I need, here are the links im lookin at.

What looks to be the same Radiator, but $20 more? I asked the seller about it, to see if I could get some answers. that $269 was the cheapest combined with shipping I could find

There is the N-flow model for $302, which is probably what ill end up getting, unless the the second link I posted is the same thing. Yeah this is pretty confusing.
