The Funk Motorsport Borg Warner K04-22 Turbo Blanket is engineered to deliver targeted heat management for vehicles equipped with the Borg Warner K04-22 turbocharger. Designed for performance enthusiasts, track-day drivers, and off-road builders, this turbo blanket helps control under-bonnet temperatures, supporting both reliability and efficiency in demanding environments.
This turbo blanket acts as a high-performance thermal barrier, containing the intense heat generated by the turbocharger's turbine housing. By minimising radiant heat loss, it helps:
Containing turbo heat is especially important for modified vehicles, track builds, and off-roaders where engine bay space is tight and component longevity is critical.
The Funk Motorsport K04-22 Turbo Blanket is ideal for:
For anyone pushing their turbocharged setup hard—whether on the circuit, in competition, or on remote trails—this blanket helps address the real-world problem of excessive heat radiating from the turbo, which can compromise reliability and performance.
According to Funk Motorsport, the 4-layer construction offers up to three times the thermal protection of many standard turbo blankets, though this is based on internal testing rather than published independent data.
Each Funk Motorsport turbo blanket is built with a proprietary 4-layer design, engineered to withstand the harsh thermal environment of a turbocharged engine bay. The choice of finish allows buyers to tailor the blanket to their build’s needs—whether prioritising durability, appearance, or ease of maintenance. The removable design is a key advantage for those who regularly inspect or service their turbocharger, reducing downtime and the risk of damaging the blanket during maintenance.
Installation is straightforward for those familiar with turbocharger systems. The blanket is designed to fit the Borg Warner K04-22 turbo precisely, but always check clearances and ensure the blanket is secured away from moving parts or direct exhaust flow. The removable feature simplifies future turbo maintenance, making this blanket a practical upgrade for both professional workshops and experienced DIY builders. Regular inspection is recommended to maintain performance and safety.
