That is the grip tuning grille. If you do a search here and just put in grip grille then you will see a ton of posts on it. It is very popular. I wouldn't buy that one off of ebay though. You can go directly to griptuning.com and buy one for the same price.
I would also go to the grip site...better to get from the people that make it....that way you are assured the warranty.I wonder if those guys are authorized to sell that grill...I noticed it says nothing about being a grip grill
