Built For High Heat Performance In Demanding Environments

The Wehrli 100732 T4 Turbo Housing Heat Blanket is engineered to endure the extreme demands of high-performance turbocharged setups. Internally rated to withstand over 2500°F of direct heat, this blanket helps maintain turbo efficiency by trapping thermal energy within the housing, allowing the turbo to spool faster and more consistently. Its high-temp exterior shell and stainless steel riveted construction ensure lasting durability, even in the harshest conditions. This blanket is designed to universally fit T4 flange turbos and works with a variety of popular units including S400, S500, GT50, GT55, and Precision T6 housings. It serves as a valuable barrier between your turbo and the rest of your engine bay, significantly lowering radiant heat and minimizing the risk of damage to nearby lines or components. The blanket comes complete and ready to install, requiring no special tools or fabrication. It’s a trusted addition for diesel builds from 1994-2018 Cummins or 2001-2016 Duramax platforms that demand both protection and performance.
