Wehrli 04.5-16 Chevrolet 6.6L LLY/LBZ/LMM/LML Duramax VGT Exhaust Housing Heat Blanket

The internal ceramic insulation in this Wehrli heat blanket is rated to withstand over 2,500 degrees Fahrenheit from a direct heat source. This well-built blanket is designed to fit tightly around the stock Variable Geometry Turbo (VGT) exhaust housing on a wide range of Chevrolet and GMC trucks, including models like the 2004-2016 Silverado and Sierra 2500 HD, and 2007-2016 3500 HD, all equipped with the 6.6L Duramax diesel engine.

By keeping the wasted thermal energy inside the turbo housing, this blanket helps maintain exhaust gas velocity. This improved flow drives the turbine more efficiently, leading to better turbocharger response and spool-up. The blanket's exterior is protected by a durable wire mesh layer for resistance to abrasion, and it's finished with a grey high-temperature shell and stainless steel rivets for a clean look over the stock turbo housing. It's handmade in the USA and is designed to be a straightforward installation, replacing the factory metal heat shield if present.
