6.6L L5P GM Duramax Turbo Blanket

Engineered specifically for the 2017–2019 6.6L L5P GM Duramax, this high-performance turbo blanket is designed to control extreme heat, protect surrounding components, and improve overall turbo and engine efficiency.

The outer jacket is constructed from a premium alumnized lava, made from pulverized volcanic rock, providing exceptional heat resistance and durability. An aluminized backing enhances radiant heat reflection, helping to keep under-hood temperatures significantly lower.

Inside, the blanket features a knitted stainless wire mesh liner for structural integrity and long-term durability. At the core is a high-density 2500°F ceramic insulation, engineered to retain exhaust heat within the turbine housing for improved turbo response and reduced heat soak.

Key Benefits:

• Designed for exact fitment on L5P Duramax turbochargers

• Lava rock fiber outer layer for extreme heat resistance and longevity

• Aluminized backing to reflect radiant heat away from engine components

• Knitted wire mesh inner liner for strength and stability

• 2500°F rated ceramic insulation for maximum thermal containment

• Reduces under-hood temperatures and protects hoses, wiring, and nearby components

Built for high-load towing, daily driving, and performance applications, this turbo blanket delivers reliable thermal management in the most demanding diesel environments.
