Product Description

The Wehrli Custom Fabrication WCF100822 VGT Turbo Heat Blanket is engineered specifically for 2017-2026 GM HD trucks equipped with the 6.6L L5P Duramax diesel engine and Variable Geometry Turbocharger. This premium turbo blanket is handmade in the USA using high-temperature insulation materials rated to withstand direct heat exceeding 2500°F, making it ideal for tuned and performance-modified trucks that generate elevated exhaust gas temperatures. By containing heat within the turbocharger housing, this blanket improves turbocharger efficiency, maintains optimal boost pressure, and significantly reduces under-hood temperatures that can damage sensitive components like wiring harnesses, rubber hoses, fuel lines, and electronic modules.

Installation is straightforward and requires removal of the factory heat shield, as the Wehrli turbo blanket is not compatible with OEM shields. The blanket wraps securely around the turbo exhaust housing and fastens with integrated stainless steel rivets that resist corrosion and maintain secure attachment even under extreme vibration and thermal cycling. The durable exterior shell material is engineered to withstand abrasion and maintain its structural integrity over years of use. Most installations can be completed in 30-45 minutes with basic hand tools. This turbo blanket is particularly beneficial for trucks running aftermarket tuning, upgraded turbochargers, or compound turbo setups where managing heat is critical for performance and reliability.

Whether you're towing heavy loads, running at the drag strip, or pushing the limits of your L5P Duramax with performance modifications, the Wehrli WCF100822 Turbo Heat Blanket provides measurable benefits in thermal management and component protection. The blanket helps reduce heat soak into the intake system, keeping intake air temperatures lower for denser air charge and better combustion efficiency. It also protects expensive components in the crowded engine bay from premature failure due to excessive heat exposure. Compatible with all 2017-2026 Silverado and Sierra 2500HD/3500HD models regardless of cab configuration, bed length, drivetrain, or trim level, this turbo blanket represents a smart investment for anyone seeking to maximize performance, protect their investment, and improve the longevity of their modified L5P Duramax truck.
