The WEHRLI CUSTOM FAB WCF100733 DURAMAX VGT TURBO HEAT BLANKET is designed to control extreme turbocharger temperatures on 2004.5-2016 GM Duramax engines. By containing heat within the turbine housing, this high-temperature insulating blanket helps reduce under-hood temperatures while improving turbocharger efficiency and protecting nearby engine components.

Duramax trucks equipped with VGT turbochargers can generate substantial heat during towing, heavy load, and performance driving conditions. The Wehrli heat blanket provides a durable barrier that helps minimize radiant heat transfer to surrounding components such as wiring, intake tubing, coolant hoses, and firewall insulation.

Constructed using multi-layer high-temperature insulation materials and stainless steel reinforcement, the WCF100733 turbo blanket is engineered to withstand extreme operating conditions. The design follows the contours of the factory Duramax VGT turbocharger to ensure a secure fit and straightforward installation.

Key Benefits:

• Reduces radiant turbo heat inside the engine bay
• Helps improve turbo efficiency by retaining turbine heat
• Protects surrounding components from heat damage
• Heavy-duty multi-layer thermal insulation construction

FAQ

What does a turbo heat blanket do?

A turbo blanket helps contain heat inside the turbine housing. This reduces engine bay heat while improving exhaust energy retention, which can improve turbocharger efficiency.

Will this fit all Duramax engines?

No. This blanket is designed specifically for 2004.5-2016 Duramax engines equipped with VGT turbochargers, including LLY, LBZ, LMM, and LML models.

Does this improve turbo performance?

By retaining heat in the turbine housing, the turbo can operate more efficiently. While not a horsepower upgrade by itself, it can help support improved turbo response and overall system efficiency.

Is installation difficult?

No. The blanket is designed to wrap around the factory turbocharger housing and secure with built-in hardware, making installation relatively straightforward for most diesel enthusiasts.

Is this recommended for towing trucks?

Yes. Trucks used for towing or heavy load conditions benefit greatly from reduced under-hood heat and improved heat management around the turbocharger.
