Hello, first of all thank you for accepting me in the 350z forum community, it's a huge honour to be a part of it!
I had the car for 3 weeks now and I can say it is incredible and so much fun to drive!
My question is the following: where do the part (plastic cover lid) from the photos fit. It should be somewhere near the front end of the car.
I know my question might sound stupid to you, but I could not figure it out myself, so I would highly appreciate your help.
Thank you!

 

They hang down on the left and right side of the bumper support using those little black push tabs

 

To add to the above description, those plastic panels are air deflectors designed to channel air towards the radiator.

 

Thanks very much to both of you!
