rotor weights giving higher redline, AFM, pressure sensors, injector plug design, VDI on N/A's, 6 port actuators move different directions, body side moldings, front and rear bumpers, mirrors, turn signal controls, gauges, thermostat housing, radio surround, shifter, shifter surround, height of the turbo spoiler, umm, let me see, i know theres more.....

Oh yea, Turn signal lenses, foglights, wheel designs, and i think thats it....

You could try reading the FAQ though, or even the FSM in the archive...

not to mention 10 blades on the S5 fan, and only 8 on the S4. The radiator is different, and even more stuff.
