The S6/S7 pulley sets are the ones that spin the water pump backwards, as well as all the cosmo motors. The atkins kit is the only serpentine set that spins the FC water pump the correct way.



You can always have the pulleys anodized any color you want.



The alternator housings are different between s4 and s5, and the plug is the same between s5 and s6, but i believe the s6 alternator is a little bigger.

Sorry for the thread hijack.. But where can you get aluminum anodized? Do you know roughly how much it costs?



If that's the case and it's not too pricey, I may get the Atkin's pulley kit anodized..
