Spoilers for the fifth door Mercedes GL-Class X164

Spoilers on the roof, on the fifth door or on the trunk lid for tuning Mercedes GL-Class X164 are usually blown, that is, having an opening or a blown plane between the car body and the spoiler surface. They have both decorative and practical functionality because due to the purging 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.
