I *believe* they will fit just fine. The water necks are a tad different, but that shouldnt affect your install.

any benefits using an S5 radiator in an S4, is it better or are they about the same??

Yep, you can easily fill the radiator completely w/o fooling with that bleed screw. That coolant buzzer has to be the most annoying sound on the planet.

When I ordered my koyo from rx7store they accidentally sent me an s5, no big whoop I figured until I tried to install it. I dunno about stock for stock but the s5 koyo is about 1/2in wider than the stock s4 one, I had to drill two new mounting holes and modify the mounting bracket a bit, but now she fits like a glove. Except until i scrounge up an s5 water neck I have two radiator caps
