Turbo Heat Protection for Borg Warner K04-23 Applications
The Funk Motorsport Borg Warner K04-23 Turbo Blanket is designed for owners and builders who demand reliable turbo heat management in high-performance, off-road, or endurance environments. This model is engineered specifically for the Borg Warner K04-23 turbocharger, providing targeted thermal protection to help maintain engine bay temperatures and support consistent turbo performance.
How the Funk Motorsport Turbo Blanket Works
Turbochargers generate extreme heat, particularly at the turbine housing. Without effective heat containment, this radiant energy can raise under-bonnet temperatures, risking heat soak, component fatigue, and reduced intake efficiency. The Funk Motorsport turbo blanket acts as a thermal barrier, helping to contain and manage this heat at its source. By insulating the turbo, it supports:
Lower engine bay temperatures
Protection for hoses, wiring, and intake components
More stable intake air temperatures
Improved turbocharger efficiency during sustained use
Where This Turbo Blanket Excels
This turbo blanket is ideal for:
Track day vehicles running Borg Warner K04-23 turbos
Off-road builds exposed to prolonged engine load and low-speed airflow
Performance street cars seeking to reduce heat soak and protect engine bay components
Owners looking for a precise fit and easy maintenance will benefit from the removable design, which allows for straightforward turbo servicing without damaging the blanket.
Key Benefits for Borg Warner K04-23 Owners
Engineered specifically for the Borg Warner K04-23 turbocharger

Titanium: Classic motorsport appearance, durable and easy to clean
Carbon Fibre: Distinctive look, matches carbon engine bay components
Inside Out: Unique reversed construction, preferred by some for installation or visual style
Choose the finish that best suits your build’s appearance or handling preference—thermal performance remains consistent across all options.
Installation and Practical Considerations
Installation is straightforward for those familiar with turbocharger systems. The blanket is designed for a snug fit on the Borg Warner K04-23 turbo, ensuring secure coverage. Always allow the turbo to cool before installing or removing the blanket.
