wasnt sure were to ask or put so here goes. Its plastic like a light cover and goes on the back hatch of you car but only covers say a foot or so. Nothing like louvers. Ive seen them but guess I need to do a google search.

 

Is it like a square or something?

 

No it follows the contour of the back hacth and covers about 6 inches down from the top. Just helps eliminate sun from getting in the the part of the hatch. Like where the lines are that are a pain in the butt to window tint for some.

 

I've seen it called a 'solar wing'. I've seen some nice ones, but most people on here don't like them, so don't take it personally...it's your car.

I hear GTS makes them or makes an aftermarket one. Good luck.
