Thermal sleeves are heat insulating tubes that wrap around hoses and wires in your vehicle. They protect these components from exposure to high engine temperatures, preventing them from becoming brittle, cracked, or melted. Thermal sleeves are also useful for reducing heat soak, which can improve performance by keeping intake temperatures cooler.  When choosing thermal sleeves, consider the diameter needed, temperature resistance, and material.
