BMW 540i B58 Turbo Blanket by Funk Motorsport

Purpose-Built Turbo Heat Shield for BMW 5 Series B58 Engines

The Funk Motorsport BMW 540i Turbo Blanket is engineered for owners seeking reliable heat management on the B58 turbocharged engine platform. Designed to fit the BMW 540i (G30/G31) models equipped with the B58 engine, this turbo blanket helps reduce engine bay temperatures, protect sensitive components, and support consistent turbo performance. Available in both Titanium and Carbon Fibre finishes, it combines robust thermal insulation with a premium appearance.

How This Turbo Blanket Improves Your BMW 540i

Turbocharged engines generate intense heat, especially during spirited driving or track use. Excessive radiant heat from the turbo can lead to heat soak, affecting intake air temperatures, and risking damage to wiring, hoses, and plastic components in the engine bay. The Funk Motorsport turbo blanket acts as a thermal barrier, containing heat within the turbo housing to:

• Reduce under-bonnet temperatures
• Support more stable intake air temperatures
• Help protect nearby engine bay components
• Allow easier access for turbo maintenance thanks to its removable design

This is especially valuable for BMW 540i owners who drive hard, run higher boost, or want to extend the life of engine bay components.

Where This Turbo Blanket Is Most Useful

This product is ideal for BMW 540i (G30/G31) B58 owners who:

• Regularly drive in hot climates or heavy traffic
• Participate in track days or performance events
• Have upgraded or tuned their B58 engine for increased power
• Want to protect their investment from heat-related wear

It is also suitable for enthusiasts who value easy maintenance, as the blanket can be removed for routine turbo inspections or servicing without damage.
