So I bought Cervini CS Style window and door scoops for my car I am a little worried about them flying off due to catching wind or air, I mean they are held on by only double sided type. Also I have seen where people have cut out the back indented section of the window scoop. Would It be better for me to cut mine out to let air through it or would it catch more air this way? Anybody have any problems losing them or coming off?:shrug:
