Air flexible nozzle. One end of the spigot is installed on the air filter inlet. Installation of the second end depends on what the car owner wants to get. In one case, the spigot is used as a snorkel and put as high as possible. This is used on off-road vehicles to prevent water and dirt from entering the engine through the air filter. On ordinary cars, the spigot is led to the bumper area and directed along the course of the car. The headwind pressure improves the conditions of air supply to the air filter inlet.
