I don't think there is a difference between the choices autozone gives you besides brand. This is considering you have them you car model and year correctly. As far as replacing it here is the service guide for it http://www.nicoclub.com/FSM/G35/Sedan/2008/HA.pdf . And check rock auto you might be able to get it cheaper then autozone
