I just bought an 04 sedan and it has the factory rims. Two of them are missing the center piece with the infinity symbol on it. I dont know what they are called so Im not really sure what to search for. Any ideas on getting this reasonably cheap or should I just go to infinity?
(i pulled this pic from the fs section in case anybody is wondering)

 

search google for infiniti center caps.

or you could probably go to a nissan/infiniti dealersheap and have replacements ordered.
