where can i get some fog lights and bumper mesh inserts from my g37 coupe front sports bumper? besides the dealer

 

Good question I would like to know that as well. I've seen on ebay these are available for the '05-'07 but they won't fit the '08 and higher due to the change in design. I found these

eBay - New & used electronics, cars, apparel, collectibles, sporting goods & more at low prices

but there would be some retrofit work that would need to be done.
