Funk Motorsport BMW 120i B48 Turbo Blanket – 1 Series Turbo Heat Shield Upgrade

BMW 120i B48 Turbo Blanket by Funk Motorsport

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.

How the Turbo Blanket Supports Your BMW 120i B48

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.

Application and Fitment Guidance

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:

• BMW 120i F20/F21 owners seeking to reduce engine bay temperatures
• Track and fast-road builds requiring consistent thermal management
• Enthusiasts aiming to protect wiring, hoses, and intake components from heat
• Projects where routine turbo inspection or servicing is important
