Using this Torque Solution Thermal Turbo Blanket is easy. First, make sure your turbo is cool. Then, simply wrap the blanket around your turbo. It's designed to fit all OEM Subaru turbos and most small - frame externally gated turbos, so it should go on smoothly. When it comes to safety, don't touch the exterior surface when the turbo is running as it can get hot. The direct contact limit is 600 Deg F / 316 Deg C. For maintenance, check the blanket regularly for any signs of wear or damage. If you notice any holes or fraying in the wire mesh or layers, it might be time to replace it. Keep it clean by gently removing any dirt or debris. This will help it keep blocking heat effectively for a long time.
