Funk Motorsport BMW 320i B48 Turbo Blanket – BMW 3 Series Turbo Heat Shield

Turbo Heat Management for BMW 320i B48 Engines

The Funk Motorsport BMW 320i B48 Turbo Blanket is engineered for owners seeking to manage under-bonnet heat, protect vital engine bay components, and support consistent turbo performance in their BMW 3 Series. Designed specifically for the B48 turbocharger found in the 320i, this turbo blanket offers a practical solution for enthusiasts who demand reliability and efficiency from their turbocharged BMW.

How the Funk Motorsport Turbo Blanket Works

This turbo blanket insulates the turbine housing of your BMW 320i’s B48 engine, helping to contain extreme heat generated by the turbocharger. By reducing radiant heat transfer, it helps lower engine bay temperatures, protecting hoses, wiring, and plastics from heat soak and potential damage. The result is a more stable thermal environment, supporting consistent turbo operation and reducing the risk of heat-related reliability issues during spirited road use, track days, or high-load driving.

Where This Turbo Blanket Makes a Difference

BMW 320i owners often encounter high engine bay temperatures, especially with tuned or hard-driven vehicles. Excessive heat can degrade components and contribute to performance loss. The Funk Motorsport turbo blanket addresses these issues by:

• Minimising heat transfer from the turbo to surrounding engine bay parts
• Supporting lower intake air temperatures for improved efficiency
• Protecting critical wiring, hoses, and plastics from heat damage
• Allowing for safer, more reliable operation in demanding conditions
