Funk Motorsport Borgwarner K03 / K04 Turbo Blanket – Turbo Heat Management

Funk Motorsport Borgwarner K03 / K04 Turbo Blanket Overview

The Funk Motorsport Borgwarner K03 / K04 Turbo Blanket is engineered for precise fitment on Borgwarner K03 and K04 turbochargers, offering advanced thermal protection for both the turbo and its adjoining exhaust manifold. Designed specifically for the complex geometry of these turbo models, this blanket delivers targeted heat management where it matters most in performance and motorsport applications.

How the Funk Motorsport Turbo Blanket Works

This turbo blanket insulates the hot side of your Borgwarner K03 or K04 turbo, minimising heat transfer into the engine bay. By containing extreme temperatures within the turbine housing and manifold, it helps prevent heat soak affecting sensitive components, wiring, and intake systems. The result is a cooler, more stable engine bay environment, supporting improved turbo efficiency and reliability during demanding driving conditions.

Where This Turbo Blanket Is Useful

The Funk Motorsport K03 / K04 Turbo Blanket is ideal for:

• Track day and motorsport builds seeking maximum heat control
• Performance road cars equipped with Borgwarner K03 or K04 turbos
• Ford and VAG platform enthusiasts looking to protect engine bay components
• Turbocharged vehicles where exhaust manifold and turbo proximity causes heat soak
• Owners aiming to reduce under-bonnet temperatures for improved intake air quality and component longevity

Key Benefits of the Funk Motorsport K03 / K04 Turbo Blanket

• Designed specifically for Borgwarner K03 and K04 turbochargers
• Insulates both turbo and exhaust manifold for double heat protection
• Helps maintain cooler intake and engine bay temperatures
• Supports improved turbo response and efficiency
• Reduces risk of heat-related damage to nearby wiring and electronics
• Widely used in motorsport and high-performance applications

Construction and Design

This Funk Motorsport turbo blanket is shaped to match the unique contours of the K03 and K04 turbo units, ensuring a secure and effective fit. The design allows coverage of both the turbo and the adjoining manifold, eliminating the need for separate manifold wraps. Materials and exact construction details are developed for high thermal resistance, supporting long-term durability under extreme conditions.

Installation Notes

The blanket is designed for straightforward installation on Borgwarner K03 and K04 turbos. It is recommended to install during turbo or manifold fitting for best access. Due to the precise fit, ensure the blanket is properly seated and secured to maximise thermal protection. No separate manifold wrap is required, simplifying the process for most builds. Always check for adequate clearance from moving or hot components after installation.
