Funk Motorsport Borg Warner K04-90 Turbo Blanket – Borgwarner Turbo Heat Shield

Advanced Heat Management for Borg Warner K04-90 Turbos

The Funk Motorsport Borg Warner K04-90 Turbo Blanket is engineered specifically for enthusiasts and professionals seeking reliable heat control for vehicles equipped with the Borg Warner K04-90 turbocharger. Designed to address the unique thermal demands of high-performance and modified builds, this turbo blanket helps manage engine bay temperatures, supporting both performance and component longevity.

How the Funk Motorsport Turbo Blanket Supports Your Build

This turbo blanket is designed to insulate the turbine housing of the Borg Warner K04-90 turbo. By containing and reducing radiant heat, it helps protect nearby wiring, hoses, and sensitive engine bay components from thermal stress. This containment also supports improved turbocharger efficiency by helping to retain exhaust energy within the turbine housing, which can be especially valuable in tuned or track-driven vehicles.
