Funk Motorsport BMW S55 Twin Turbo Blankets For BMW F80 M3, F82/F83 M4 & F87 M2 Competition

Enhance thermal efficiency and protect your engine bay with the Funk Motorsport BMW S55 Twin Turbo Blankets – precisely developed for the twin-turbo setup in the F80 M3, F82/F83 M4, and F87 M2 Competition. These premium turbo blankets are crafted to reduce under-bonnet temperatures, improve turbo performance, and shield nearby components from extreme heat, making them an essential upgrade for both performance and longevity.

Constructed using advanced multi-layer materials, including a volcanic rock-based outer layer, stainless steel internal mesh, and a highly insulative core, these blankets are capable of withstanding continuous temperatures of up to 1300°C. By retaining heat within the turbo housings, they promote faster spool-up and reduce heat soak, improving overall throttle response and engine efficiency.

Each kit is tailored specifically for the BMW S55 engine and comes supplied as a pair – one for each turbo – along with stainless steel locking wire for secure installation. Developed and tested in the UK, these turbo blankets are trusted by enthusiasts and tuners alike for their durability and performance benefits.

Notably, these turbo blankets are not single-use and can be removed and refitted during routine servicing.
