Funk Motorsport Turbo Blanket – BMW M240i (G42) B58 Engine

The Funk Motorsport turbo blanket for the BMW M240i (G42) with the B58 engine is engineered to improve performance, reduce under-bonnet temperatures, and protect critical components from excessive heat. Designed for direct fitment, this blanket insulates the hot side of the turbo, retaining exhaust energy for quicker spool and sharper throttle response.

Performance

• Improves gas velocity and turbo efficiency

• Reduces turbo lag by increasing exhaust gas temperature retention

• Lowers under-bonnet temperatures to reduce intake heat soak

• Enhances consistency of power delivery, especially under repeated high-load conditions

Protection

• Shields nearby components such as oil and coolant lines, intake pipework, and bodywork

• Reduces radiant heat damage to sensitive electronics and hoses

• Helps maintain cooler intake temps for better combustion efficiency

Reliability

• Minimises engine bay heat soak, improving overall engine system reliability

• Lowers temperatures in coolant, fuel, and oil lines for long-term performance stability

• Prolongs the life of surrounding materials and components

Why Funk Motorsport?

• 4-layer construction for advanced heat retention and durability

• Upgraded internal insulation using ceramic-silica matting – up to 3x better heat reduction

• High-temp stainless steel thread (1mm) rated to 1300°C for long-lasting durability

• Exterior available in Carbon Fibre or Titanium twill finish

• ROHS tested and approved

Important Note
While the blanket itself is non-flammable, it may become an ignition source if exposed to flammable fluids. Ensure proper maintenance of all nearby fuel and oil lines. Funk Motorsport is not responsible for misuse or contamination of the blanket.
