The Funk Motorsport Turbo Blanket is precision-engineered for the BMW 120i fitted with the B48 engine, offering targeted heat management for owners who demand more from their turbocharged 1 Series. Designed for enthusiasts, track-day drivers, and anyone seeking to protect their engine bay from excessive heat, this turbo blanket combines advanced materials with a unique removable construction for ongoing maintenance access.
Modern turbocharged engines like the BMW B48 generate significant heat, which can lead to heat soak, reduced turbo efficiency, and premature wear on nearby components. The Funk Motorsport Turbo Blanket insulates the turbocharger, containing radiant heat within the turbine housing. This helps maintain optimal turbo temperatures, supports faster spool, and reduces the risk of heat-related issues in the engine bay—especially during spirited driving, track use, or demanding road conditions.
This turbo blanket is specifically designed for the BMW 120i equipped with the B48 engine, covering F20 and F21 chassis models produced from 2015 onwards. If you own a 1 Series with the B48 engine (2015+), this blanket is tailored to fit the factory turbocharger. For other B48-powered BMWs or modified setups, confirm turbocharger compatibility before purchase. This product is ideal for:
Funk Motorsport's turbo blanket features a robust four-layer construction, combining advanced heat-resistant materials to maximise insulation. The removable design is a standout feature, allowing the blanket to be taken off for turbo inspection or servicing—ideal for high-mileage or performance builds. Choose between Titanium or Carbon Fibre finishes to match your engine bay aesthetic, with both options delivering the same level of thermal protection.
Installation is straightforward for those familiar with basic engine bay work. The blanket is designed to fit the factory B48 turbocharger on the BMW 120i F20/F21. Always ensure the turbo is cool before installation or removal. For modified turbo setups or other B48-powered models, check compatibility before ordering. Routine inspection after hard use is recommended to ensure ongoing performance.

DIY installation is possible for experienced owners, but professional fitting is recommended for best results and to ensure correct placement.
Both finishes offer the same thermal protection; the choice is purely aesthetic to match your engine bay style.
Routine inspection after heavy use is advised, but the blanket is designed for durability and long-term performance.
Check dimensions, mounting points, clearance and any wiring or hose requirements against your setup before ordering.
