Thermal Zero Premium Fitted Turbocharger Heat shields go above and beyond when it comes to heat tolerance and durability. The inner layer of the heat shield can handle over 2000 degrees Fahrenheit of direct heat. The shields are made of 1 inch of ceramic insulation material and covered with a silicone based outer shell that is colored either Black, Red, Chrome, or Gray. Since vibration on a motor is inevitable we have created a more durable design. Our turbo shields feature a wire mesh inner layer that separates the insulation material from the turbocharger housing, greatly increasing durability and reducing breakdown.
