You can look at the number of fan blades, waterpump neck and omp.

S5's have 10 fan blades and s4's have 8 I think.

S4's have a metal waterpump necks while s5's are plastic.

S4's have mechanical omp's and s5's have electronic ones.

On the s4 housings there are some writing on the top. The s4 has a totally different intake from the s5.
