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.
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:
This turbo blanket is ideal for:
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.
The Funk Motorsport K04-23 Turbo Blanket is available in three finishes. All finishes provide the same core thermal protection and performance. The choice of finish is primarily aesthetic and for handling preference:
Choose the finish that best suits your build’s appearance or handling preference—thermal performance remains consistent across all options.
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. The removable design means routine inspection and maintenance are simple, making it suitable for both professional workshops and experienced enthusiasts.
