Yeah I still have them, I posted a sale thread which didn't go well as it is an overpriced part and the one I have is authentic
It is designed to get air directly to oem boxes, I was planning for short rams and they would be very useful, but now I am not sure if they will give the CAI more air.
This is how they look, and they are very very light (small part and dry carbon)
During summer I will check it again and will try to give the Z a body refresh, either a full bodykit or addon parts. So, I will see where the air will go and how I can make them provide more air to the intakes.
