Both work great. Fluidyne is a bit smaller than the Koyo. Theres several posts about this before, theres a slight chance Koyo might not fit depending on what you have, you might have to do a little modifying. Koyo is like $340 and Fluidyne is like $450+.

The only problem with the Koyo is it makes everything like the stock intercooler sit higher.

save some bucks and simply get a Radiator World stock replacement. All metal construction, about 20% larger than stock but with a PERFECT drop-in fit.
No sense in spending big bux on a radiator, and keep in mind that both your choices will actually have POORER performance in most driving conditions than the stock.

The newer Koyo N-Flow works great, Fluidyne will always be a good choice. Fluidyne is slightly better fittement just because of the thickness, but if your on a budget I would go with Koyo because I haven't seen any performance problems with them.

In terms of stop and go traffic, a bigger radiator isn't always better.
