I am currently doing an audio build in my 2013 and could not find the perfect matching carpet to match the factory parts. I finally found it.
I figured that I would post it up here for anyone with my same OCD that is looking for the carpet for some reason. Maybe you need to make a repair or something.
It is called 2078 special graphite from yourautotrim.com
It will match the cargofloor cover and all the cargo area carpeted areas. The rest of the floor carpeting in the front is the same color but a little bit of a different texture so it might look a little different. If you are making a part for the jeep I would suggest spraying the surface black first since this carpet could allow colors behind it to show through very slightly.
Okay here it is.
