The Funk Motorsport Cummins 5.9L ISB Turbo Blanket is engineered to deliver advanced thermal management for your turbocharged Cummins engine. Designed specifically for the 5.9L ISB platform, this turbo blanket helps contain and manage the extreme heat generated by the turbocharger, supporting both performance and engine bay protection in demanding environments.
This product insulates the turbocharger’s turbine housing, significantly reducing radiant heat transfer into the engine bay. By keeping heat contained within the turbo, the blanket helps improve turbo efficiency, supports lower intake temperatures, and protects nearby components from heat soak and potential damage.
Owners of Cummins 5.9L ISB engines—whether in road, off-road, or motorsport applications—will benefit from improved thermal control. This blanket is especially valuable for builds where engine bay temperatures can impact reliability, such as in towing, heavy-duty work, or performance tuning scenarios. It is also ideal for those seeking to enhance turbo longevity and reduce the risk of heat-related failures in wiring, hoses, and plastics near the turbo.
The Funk Motorsport Cummins Turbo Blanket features a proprietary 4-layer construction, providing up to three times more thermal protection compared to typical competitor blankets. Available in multiple finishes—Titanium, Carbon Fibre, and Inside Out—each variant is built for durability and high-temperature resistance. The design is the first in the world to allow easy removal for routine turbo maintenance, supporting both performance and serviceability.
This turbo blanket is tailored for the Cummins 5.9L ISB turbocharger. Installation is straightforward, but care should be taken to ensure a secure fit around the turbine housing. The removable design means you can access the turbo for inspection or servicing without damaging the blanket, making it suitable for both professional workshops and hands-on enthusiasts. Always allow the engine to cool before attempting removal or installation.
