Funk Motorsport Borgwarner S300 Turbo Blanket – S300 Series Turbo Heat Management

Funk Motorsport S300 Turbo Blanket for Borgwarner S300 Series

Purpose-Built Heat Management for S300 Turbos

The Funk Motorsport Borgwarner S300 Turbo Blanket is engineered specifically for the S300 series turbocharger range, offering targeted thermal protection for high-performance, motorsport, and off-road builds. This product is designed for owners and builders seeking to control under-bonnet temperatures, protect vulnerable components, and support consistent turbocharger performance in demanding environments.

How the S300 Turbo Blanket Improves Your Build

Turbochargers generate extreme heat, especially under sustained load or repeated boost cycles. Without effective insulation, this heat can soak into wiring, hoses, and intake components, risking reliability and reducing overall efficiency. The Funk Motorsport S300 Turbo Blanket helps contain this heat within the turbo’s turbine housing, reducing radiant temperatures and supporting safer, more stable engine bay conditions. This is especially valuable for S300-based builds where space is tight or thermal management is a known challenge.

Application and Fitment Guidance

This turbo blanket is designed to fit Borgwarner S300 series turbochargers, including popular S360, S366, S372, and S300SX variants. It is suitable for use in motorsport, off-road, and high-output road applications where the S300 turbo platform is used. For custom or hybrid S300 configurations, check turbo housing dimensions before purchase to ensure optimal fitment. If your build uses a different Borgwarner turbo, refer to the Funk Motorsport Borgwarner Turbo Blankets collection for alternative options.
