Are you looking for an 8 rib pulley or is your current pulley damaged?
i'm not sure but 4.6 and other models are probably the same. Take your stocker when you go and compare them.
Dude go to autozone and its like $15 bucks, its a dorman pulley, its more of hassle to take that damn pulley out, sometimes if your not carefull you will break the tool while removing/installing the pulley so be very carefull!
