I have a 2004 G35 Coupe, and on the dash around volume and the up/down buttons to choose the temp. you want both have chrome finished rings around them just to look nice, well i was at one of the vacuum booth and was getting all the dog hair and dust out of my car and the little chrome ring shot up right into the hose and into the tunnel of death.. Can someone point me in the direction of where to get a new one I have no clue what its even called.

 

I doubt that piece can be ordered separately. Your best bet for finding a new one (if it is separate) would be from Grubb's Infiniti or another of the dealers who support this board. If you can't get it that way, junkyards or picking up the trim on the marketplace from somebody who did the DDin upgrade is the way to go.
