The Funk Motorsport Turbo Blanket is engineered for the BMW X4 M40i fitted with the B58 engine, providing targeted thermal insulation for the turbocharger. By helping to contain extreme heat within the turbo housing, this blanket reduces radiant heat exposure in the engine bay. The result is improved protection for sensitive wiring, hoses, and plastic components, supporting both reliability and consistent turbo performance during spirited driving or demanding conditions.
This turbo blanket is designed specifically for the BMW X4 M40i with the B58 engine, covering model years typically from 2018 onwards (G02 chassis). It is ideal for owners seeking to manage under-bonnet temperatures, whether for daily driving, track days, or performance builds. If you own a different B58-powered BMW (such as the 3 Series or 5 Series), please confirm fitment or explore Funk Motorsport's dedicated turbo blanket range for your model. No part number is specified; always check compatibility before purchase.
Turbocharged engines like the B58 generate significant heat, especially under load. Excessive radiant heat can degrade plastics, wiring, and hoses, and may lead to heat soak that affects performance and reliability. The Funk Motorsport turbo blanket helps address this by containing heat at the source, allowing your X4 M40i to perform more consistently in both everyday and high-demand scenarios.
Funk Motorsport's signature 4-layer construction is designed to offer enhanced thermal insulation compared to many standard turbo blankets. The removable design is a practical advantage, allowing the blanket to be taken off for turbo inspection or servicing without damage. Choose between Titanium or Carbon Fibre finishes for a premium look and feel.
This turbo blanket is tailored for the B58 turbocharger in the BMW X4 M40i. Installation is straightforward and does not require permanent modifications. For best results, ensure the turbo surface is clean and follow the provided installation instructions. While professional installation is not strictly required, those unfamiliar with turbo heat management products may benefit from expert fitting.
