Sleeves are precision-engineered components designed to channel airflow to critical parts of a vehicle, such as the engine, brakes, or other components that need cooling. They are available in various materials and sizes to fit the specific requirements of your vehicle.
When shopping for sleeves, consider the material, size, and the amount of airflow improvement you need for your vehicle. Cylinder sleeves, also known as a cylinder liner, are a critical part of the engine block. These cylinder liner sleeves are used in both gasoline and diesel engine sleeves. For high-performance applications, you might also be looking for racing engine sleeves. In some cases, a dry engine sleeve is used when the sleeve is not in direct contact with the coolant.
