The Funk Motorsport Borg Warner K04-20 Turbo Blanket is purpose-built for owners and tuners running the popular Borg Warner K04-20 turbocharger. This turbo heat shield is designed to address the real-world challenges of engine bay heat, offering targeted protection for high-performance, track, and demanding road builds where thermal management is critical for reliability and efficiency.
Turbochargers generate intense heat, which can soak into surrounding components, wiring, and intake systems. The Funk Motorsport K04-20 Turbo Blanket insulates the turbine housing, helping to contain radiant heat within the turbo itself. This reduces under-bonnet temperatures, minimises heat soak to nearby parts, and supports more consistent turbocharger efficiency—especially under sustained load or repeated boost cycles.
This product is ideal for:
By maintaining a cooler engine bay, the blanket helps prevent premature wear of hoses, wiring, and sensors, and can contribute to safer, more reliable operation in tuned or modified vehicles.
Funk Motorsport’s four-layer construction is designed to provide enhanced thermal insulation compared to standard turbo blankets. The choice of premium finishes—Titanium for classic durability, Carbon Fibre for a modern look, or Inside Out for a distinctive appearance—allows you to match your build’s style and requirements. The removable design is particularly useful for those who regularly service or inspect their turbocharger.
This turbo blanket is designed for direct fitment to the Borg Warner K04-20 turbocharger. Installation is straightforward with basic hand tools. For best results, ensure the blanket is securely fastened and does not interfere with moving parts. Routine inspection after high-heat cycles is recommended, especially in motorsport or heavy-duty applications. The removable design makes servicing your turbo easier and more cost-effective.
