Product Description
The WEHRLI CUSTOM FAB WCF100822 2017-2024 L5P DURAMAX VGT TURBO HEAT BLANKET is designed to control one of the biggest enemies of diesel performance — excessive turbo heat. By containing heat inside the turbine housing, this high-quality turbo blanket helps improve turbo efficiency while lowering underhood temperatures on high-performance L5P Duramax trucks.
Turbochargers generate extreme heat under heavy load. Without proper containment, this heat radiates into the engine bay and can affect surrounding components such as wiring, intercooler piping, sensors, and coolant lines. The Wehrli turbo blanket helps trap that heat inside the turbine housing where it belongs, helping improve spool efficiency while protecting surrounding components.
Built with a durable high-temperature outer shell and internally rated to withstand temperatures exceeding 2500°F of direct heat, this turbo blanket is designed for high-performance and competition Duramax builds. Stainless steel riveted fasteners ensure the blanket stays securely in place even under aggressive driving conditions.
This upgrade is especially beneficial for tuned L5P trucks running increased boost, upgraded fueling, or performance turbo systems where turbo heat management becomes critical.

FAQ
What does a turbo heat blanket do?
A turbo heat blanket traps heat inside the turbocharger housing instead of allowing it to radiate into the engine bay. This helps improve turbo efficiency while protecting nearby components from excessive heat.
Will this fit all L5P Duramax trucks?
This blanket is designed for 2017-2024 GM Silverado and Sierra trucks equipped with the 6.6L L5P Duramax using a VGT style turbocharger.
Does this blanket improve turbo performance?
Yes. By retaining heat within the turbine housing, exhaust energy stays concentrated which can improve turbo spool efficiency while reducing heat soak under the hood.
Is the factory turbo heat shield required?
No. In fact, the blanket is designed to replace the factory heat shield and is not compatible with the OEM shield installed.
Is this safe for high horsepower builds?
Yes. The blanket is internally rated for temperatures exceeding 2500°F and is designed for high-performance or competition Duramax applications.
