The Funk Motorsport Borg Warner K04-25 Turbo Blanket is engineered for enthusiasts and professionals demanding precise heat control in high-performance, track, or off-road builds running the Borg Warner K04-25 turbocharger. This turbo blanket is part of Funk Motorsport’s advanced heat management range, designed to protect critical engine bay components and support consistent turbo performance.
Turbochargers generate intense heat, especially under sustained load or during aggressive driving. Without effective insulation, this heat radiates into the engine bay, risking damage to wiring, hoses, and sensitive electronics. The Funk Motorsport K04-25 Turbo Blanket is designed to contain heat at the turbine housing, reducing radiant temperatures and helping maintain optimal turbocharger efficiency. By keeping more heat within the turbo, the blanket supports improved spool response and helps protect surrounding components from premature wear or failure.
This turbo blanket is specifically tailored for vehicles equipped with the Borg Warner K04-25 turbocharger—commonly found in performance-tuned road cars, track builds, and off-road conversions. It is especially valuable for:
If you are upgrading your turbo system or experiencing heat soak, this product helps address those challenges by supporting cooler, safer, and more reliable engine bay operation.
The Funk Motorsport K04-25 Turbo Blanket features a multi-layer construction, using advanced thermal barrier materials chosen for their durability and heat resistance. The removable design is a unique feature that allows for ongoing turbo maintenance—a practical advantage for motorsport and enthusiast applications. Choose from Titanium, Carbon Fibre, or Inside Out finishes to match your build’s needs and style.
Installation is straightforward and typically requires only basic hand tools. The blanket is designed for a snug fit on the Borg Warner K04-25 turbo, but always check for proper clearance and secure attachment. Regular inspection is recommended, especially in high-heat or motorsport environments, to ensure continued effectiveness and safety. The removable design means you can access the turbo for servicing without damaging the blanket—ideal for vehicles that see frequent tuning or track use.
