The Funk Motorsport BMW 340i B58 Turbo Blanket is engineered for owners seeking to manage under-bonnet heat and support turbocharger efficiency in their BMW 3 Series. Designed specifically for the B58 turbocharger found in the 340i, this heat shield helps protect sensitive engine bay components and maintain consistent performance, whether your car is daily driven, tuned, or track-prepped.
Turbochargers generate intense heat during operation, which can raise engine bay temperatures and risk heat soak. This turbo blanket acts as a thermal barrier, insulating the turbo housing to help reduce radiant heat transfer. By keeping heat contained, it helps protect wiring, hoses, and plastics, and supports more stable intake temperatures for improved reliability and performance.
This turbo blanket is ideal for BMW 340i owners with the B58 engine who:
Whether your 340i is stock or upgraded, this product helps maintain lower under-bonnet temperatures and supports long-term reliability. It is especially useful for builds where engine bay heat is a known concern or where additional thermal management is required for supporting modifications.
The Funk Motorsport turbo blanket features a robust multi-layer construction, designed to deliver effective thermal insulation for the B58 turbocharger. Both Titanium and Carbon Fibre finishes are available, allowing you to match your engine bay’s style and performance needs. The removable design supports routine turbo servicing without damaging the blanket.
This turbo blanket is tailored for the BMW 340i with the B58 engine. Installation is straightforward and can be completed with standard hand tools. The removable feature means you can access your turbo for inspection or maintenance without needing to replace the blanket. Professional installation is recommended for best results, especially on modified vehicles.
