the S4 and S5 looks the same.
The 6 ports are the same.
You can distingish the 4 ports from the turbo and the 4 ports early n/a because the water passages are different at the exhaust area.
The 3rd gen irons looks different that the S4 and the S5 4 ports because the intake port is inclined downwards.

I heard the s4 intake ports are a bit larger than the s5, also the later year rear s5 iron is reinforced at the oil filter pedastal. Also the intermediary s4 iron has a EGR valve spot wheras the S5 EGR is on the LIM.
