Spoilers for the fifth door

Spoilers on the fifth door or on the trunk lid of the BMW X5 Series E53, as a rule, are blown, that is, having an opening or a blown plane between the car body and the surface of the spoiler. They have both decorative and practical functionality, because thanks to the blowing plane, an area of low pressure is created during the movement of the car and, as a result, air turbulence by pressure, actively preventing contamination of the rear part of the car body.
