Funk Motorsport BMW N55 Turbo Blanket For BMW F87 M2, M135i, M235i, 335i, 435i & more

Optimise heat management and protect your engine bay with the Funk Motorsport Turbo Blanket for BMW models equipped with the N55 single-turbo engine. Designed to fit perfectly over the factory twin-scroll turbocharger, this high-performance thermal barrier significantly reduces under-bonnet temperatures, helping to protect critical components and improve turbo efficiency.

Constructed from advanced heat-resistant materials including a volcanic rock-based outer layer and a multi-layer stainless steel mesh interior, this turbo blanket is capable of withstanding continuous temperatures of up to 1300°C. By containing heat within the turbocharger housing, the blanket enhances spool-up, minimises heat soak, and increases overall engine reliability — particularly valuable for tuned or hard-driven vehicles.

Developed and tested in the UK, this blanket is a direct fit for all N55-powered BMWs and is a must-have upgrade for anyone looking to improve thermal control without compromise. Supplied with stainless steel locking wire for secure fitment.

Notably, this turbo blanket is not single-use and can be removed and refitted during routine servicing.
