The Funk Motorsport L5D 6.6L Duramax Turbo Blanket is engineered specifically for the L5D 6.6L Duramax turbocharger, delivering advanced heat management for demanding off-road, towing, and performance applications. Designed with Funk Motorsport’s signature four-layer construction, this turbo blanket helps control under-bonnet temperatures, supporting both reliability and efficiency in high-output diesel builds.
This turbo blanket is designed to insulate the turbine housing of the L5D 6.6L Duramax turbo. By containing radiant heat within the turbo, it helps reduce heat soak to surrounding engine bay components, minimises the risk of heat damage to wiring and hoses, and supports more consistent intake air temperatures. The result is improved turbo efficiency, enhanced protection for nearby components, and a more stable engine environment under load.
This product is ideal for owners of vehicles equipped with the L5D 6.6L Duramax engine who demand more from their builds—whether for heavy towing, off-road expeditions, or high-performance street use. It is particularly valuable where prolonged engine loads and high exhaust temperatures are common, such as in modified trucks, expedition rigs, or workhorse vehicles operating in harsh conditions.
The Funk Motorsport L5D 6.6L Duramax Turbo Blanket features a unique four-layer construction, offering up to three times more thermal protection than typical turbo jackets. Available in multiple finishes, including Titanium, Carbon Fibre, and Inside Out, each blanket is designed for durability and long-term performance in harsh environments. The removable design is a world-first, allowing for easy access during turbo maintenance without compromising the blanket’s integrity.
Installation of the Funk Motorsport turbo blanket is straightforward for those familiar with turbocharger systems. The removable design simplifies future turbo inspections and servicing. For best results, ensure the blanket is fitted securely around the turbine housing, avoiding contact with moving parts. This product is intended for the L5D 6.6L Duramax turbo; always confirm compatibility with your specific turbo model before purchase.
