The Funk Motorsport BMW 440i B58 Turbo Blanket is engineered to deliver superior heat management for your BMW 4 Series. Designed specifically for the B58 engine platform, this turbo blanket supports both performance and longevity by controlling extreme turbine temperatures in demanding road, track, and off-road environments.
This turbo blanket acts as a thermal barrier, containing heat within the turbocharger's turbine housing. By reducing radiant heat in the engine bay, it helps protect sensitive components, minimises heat soak, and supports more consistent turbo performance. The result is improved reliability and the potential for better power delivery, especially during sustained spirited driving or heavy load conditions.
The Funk Motorsport turbo blanket is ideal for BMW 440i owners who:
Whether you are building a street-driven 440i or preparing for motorsport use, this blanket is designed to meet the demands of enthusiasts who prioritise performance and protection.
Funk Motorsport's signature four-layer construction is at the heart of this turbo blanket. Each layer is designed to maximise thermal insulation, helping to keep heat where it belongs—inside the turbo housing. Choose from Titanium or Carbon Fibre finishes for both performance and visual appeal. The blanket is built to withstand the high temperatures generated by the B58 turbo, ensuring durability and long-term effectiveness.
This turbo blanket is designed for straightforward installation on the BMW 440i B58 turbocharger. Its removable design makes it easy to access the turbo for inspection or maintenance, a unique feature among turbo blankets. For best results, ensure the turbo surface is clean before fitting the blanket. Routine checks are recommended to maintain optimal performance and safety.
