So today I was driving around LI and I saw a 3.5 altima with a sunroof, but no sunroof deflector.. I thought it looked pretty sweet. I have a sunroof deflector for my sunroof now, but since seeing the way the car looks without it I think I want to remove mine. The question is, what does the sunroof deflector actually do? what is its purpose? Is there a great noticable difference when the sunroof is open without the deflector?
