Just curious if anyone has compared the pulley you get from the dealer and the cheap one fom Rockauto. I think the cheap one is hard plastic with NGK bearings. I am need to replace my stock one and would like to save the money if they are equivalent. I know there is a small push for "C3 Pulley Saver" kit but it's not here and I need it now. Anyone wanna chime in, please.
