Funk Motorsport BMW 440i B58 Turbo Blanket – Turbo Heat Management

Funk Motorsport Turbo Blanket for BMW 440i B58 Engine

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.

How the Turbo Blanket Improves Your BMW 440i

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.
