A car side vent garnish is a decorative trim piece that is located on the side of a car's exterior. It is typically located near the front wheel well or behind the front fender. The garnish is designed to enhance the appearance of the car and add a touch of style and elegance. It can be made from various materials such as chrome, plastic, or painted metal, and is available in a variety of shapes and sizes to fit different car models. The side vent garnish may also provide ventilation to the car's engine or brake systems, allowing for improved airflow and cooling.
