Funk Motorsport Subaru STI Turbo Blanket – Subaru Turbo Heat Management

Subaru STI Turbo Blanket by Funk Motorsport

Purpose-Built Heat Management for Subaru STI Turbos

The Funk Motorsport Subaru STI Turbo Blanket is engineered for owners seeking to control under-bonnet heat and protect critical engine bay components. Designed specifically for Subaru STI turbocharger applications, this blanket helps maintain a cooler, safer engine environment—whether on the road, track, or trail. By insulating the turbo’s turbine housing, it supports consistent turbo performance and helps extend the life of surrounding parts.

How This Turbo Blanket Supports Subaru Turbo Systems

Turbochargers generate intense heat, which can raise engine bay temperatures and threaten wiring, hoses, and plastics. The Funk Motorsport blanket wraps directly around the turbo’s hot side, reducing radiant heat transfer. This containment helps:

• Lower under-bonnet temperatures for improved reliability
• Protect sensitive components from heat exposure
• Minimise heat soak that can affect turbo efficiency
• Support consistent performance during spirited or prolonged driving

This upgrade is especially valuable for Subaru STI owners who drive hard, participate in motorsport, or want extra peace of mind for daily use.

Where the Funk Motorsport Subaru STI Turbo Blanket Excels

This turbo blanket is ideal for:

• Subaru WRX STI owners seeking improved engine bay heat management
• Track day and motorsport builds where thermal control is critical
• Drivers in hot climates or those running higher boost levels
• Anyone looking to protect wiring, hoses, and plastic components from heat damage

By maintaining lower engine bay temperatures, the blanket helps reduce the risk of heat-related failures and supports the longevity of your turbo system.
