Sleeves are precision engineered components that channel airflow towards a vehicle's engine, brakes, or other components that require cooling.  They are available in a wide variety of materials and sizes to suit the specific needs of your vehicle. Consider the material, size, and desired airflow improvement when selecting sleeves for your vehicle.
