Wehrli 04.5-16 Chevrolet 6.6L LLY/LBZ/LMM/LML Duramax VGT Exhaust Housing Heat Blanket
Protect sensitive underhood components and retain critical exhaust heat in your 2004.5-2016 Chevrolet 6.6L Duramax diesel with the Wehrli Custom Fabrication VGT Exhaust Housing Heat Blanket. Compatible with LLY, LBZ, LMM, and LML Duramax engines featuring the Variable Geometry Turbocharger (VGT), this premium heat blanket wraps the turbocharger exhaust housing to reduce radiated heat and protect nearby wiring, hoses, and plastic components from heat damage.
The WCF100733 heat blanket also helps keep exhaust gases hotter inside the turbine housing, which improves turbocharger efficiency and spool response — particularly beneficial in cold weather or high-demand towing conditions. CNC-precision formed to fit the Duramax VGT housing, installation requires no modifications.
