Funk Motorsport Holset HX40 Turbo Blanket – Turbo Heat Shield

Funk Motorsport Holset HX40 Turbo Blanket Overview

The Funk Motorsport Holset HX40 Turbo Blanket is engineered specifically for Holset HX40 turbochargers, providing advanced thermal protection for demanding motorsport, off-road, and high-performance applications. Designed with Funk Motorsport’s signature 4-layer construction, this turbo blanket helps manage extreme heat generated by the turbo, supporting both performance and reliability in harsh engine bay environments.

How the Funk Motorsport HX40 Turbo Blanket Works

This turbo blanket insulates the turbine housing of your Holset HX40, reducing radiant heat transfer into the engine bay. By containing exhaust-side temperatures, it helps maintain cooler intake air, protects sensitive engine components, and supports consistent turbo efficiency. The result is a more controlled thermal environment, which is especially important for builds running high boost or extended load periods.

Where the HX40 Turbo Blanket Is Most Useful

Owners of vehicles equipped with Holset HX40 turbos—whether for track, off-road, or road performance—will benefit from the improved heat management this blanket provides. It is particularly valuable for:

• Motorsport and competition vehicles requiring maximum reliability under sustained load
• Off-road builds where underbonnet temperatures can threaten wiring, hoses, and electronics
• Performance road cars seeking to reduce heat soak and improve intake air temperatures
• Turbocharged engines with limited engine bay airflow or close-proximity components
