Will add my carbon fiber NACA duct DIY to this thread, hope you don't mind.
Bought for 10 bucks of craigslist.
![](http://www.t-netzone.net/miata/nacalid/_MG_6190.jpg)
Made scratches on the lid where bondo will go onto.
Then taped the duct side where it will bondo to the lid (so I can lift it off later after the bondo). Then taped it onto the lid.
![](http://www.t-netzone.net/miata/nacalid/_MG_6203.jpg)
Taped the opening.

Side shot of the gap that needs to be filled with bondo.

Filled the gap with bondo, then took off the duct.
![](http://www.t-netzone.net/miata/nacalid/_MG_6206.jpg)
Wet sanded to a smooth surface.
![](http://www.t-netzone.net/miata/nacalid/_MG_6207.jpg)
Epoxied glue the NACA Duct to the bondo surface. Then can spray painted it with a few coats at a time.
![](http://www.t-netzone.net/miata/nacalid/_MG_6214.jpg)
Wet sanded the paint and then layed 3 layers of clear coat afterward. Then wetsanded again to smooth out bumps. Then compound waxed it to a glossy shine.
![](http://www.t-netzone.net/miata/nacalid/_MG_6232.jpg)
Peeled off the taped section.

Used the small net grill section that came with the bondo for the rear, (bent the piece to a soft corner "S" shape) and used epoxy to hold it to the back of the lid piece.
![](http://www.t-netzone.net/miata/nacalid/_MG_6244.jpg)
Laid down some more glossy wax and "Ready for my close-ups."

Since this is the unofficial "post your NACA ducted headlight lid" thread, here's mine.
- 3" duct
- JB weld as adhesive and filler
- flat-blacked the sides of the duct
It came out just okay. If I were truly baller I'd have done like Pharo_X did and repaint the lid.

Looking back through the thread, most aren't as inboard as mine. Mine's about as far back and as inboard as you can get too, I had to cut the bolt the housing pivots on for clearance..
