The Funk Motorsport Induction Kit Thermal Barrier Sleeving is designed to shield your induction tubing from excessive engine bay heat. By forming a thermal barrier around your intake pipework, it helps reduce the transfer of radiant and conductive heat, supporting cooler and denser air delivery to the engine. This can help maintain consistent intake temperatures, especially during spirited driving, track sessions, or in off-road environments where under-bonnet heat is a concern.
This sleeving is ideal for performance builds, track cars, drift vehicles, and off-road machines where the intake system is routed close to heat sources such as exhaust manifolds, turbochargers, or radiators. It is particularly useful for:
By helping to keep intake air cooler, the sleeving supports more predictable engine performance and can reduce the risk of heat-related power loss.
Funk Motorsport’s thermal barrier sleeving is engineered for durability and flexibility, allowing easy installation over most induction tubes. While specific material composition and temperature ratings are not published, the product is built to withstand the thermal demands of motorsport and high-performance applications. The sleeving’s construction is intended to maintain its protective qualities over time, even under repeated heat cycles.
Installation is straightforward: simply slide the sleeving over the induction tubing, focusing on sections exposed to significant heat. The flexible design suits a range of tube diameters and bends. For best results, secure the ends with clamps or ties as needed. No specialist tools are required, and most users can complete the installation in under an hour. Routine inspection is recommended to ensure the sleeving remains intact and properly positioned.
In high-performance and off-road vehicles, engine bay heat can quickly raise intake air temperatures, leading to reduced power and inconsistent throttle response. The Funk Motorsport Induction Kit Thermal Barrier Sleeving addresses this by providing a practical, easy-to-fit solution that helps insulate the intake path from ambient heat, supporting more stable engine performance and greater confidence in demanding conditions.

It acts as a thermal barrier, reducing the amount of heat transferred to your induction tubing, which helps keep intake air cooler and supports more consistent engine performance.
The sleeving is designed to be flexible and accommodate most standard and aftermarket induction tubes. Check your intake diameter and length to ensure compatibility.
Yes, the sleeving is engineered for use in both daily-driven vehicles and high-demand motorsport or off-road builds where intake heat management is critical.
Minimal maintenance is needed. Inspect periodically for wear or displacement, and clean with a damp cloth if necessary.
The primary function is thermal protection; it does not typically alter intake sound or restrict airflow when correctly installed.
Pairing with additional heat management solutions, such as turbo blankets or exhaust wraps, can further enhance engine bay thermal control and overall intake efficiency.
Check dimensions, mounting points, clearance and any wiring or hose requirements against your setup before ordering.
