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
  • Motorsport applications requiring robust, removable heat shielding for routine turbo inspection

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
  • Helps reduce under-bonnet heat and risk of heat soak
  • Supports consistent turbocharger performance and reliability
  • Removable design for easy turbo maintenance
  • Available in three finishes: Titanium, Carbon Fibre, and Inside Out

Finish Options: Functional and Aesthetic Differences

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:

  • 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. The removable design means routine inspection and maintenance are simple, making it suitable for both professional workshops and experienced enthusiasts.
