Funk Motorsport Turbo Blanket for Cummins 5.9L ISB Engines
How the Funk Motorsport Turbo Blanket Enhances Your Cummins 5.9L ISB
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.
What This Turbo Blanket Does
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.
Where the Funk Motorsport Cummins Turbo Blanket Is Most Useful
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.
