Funk Motorsport BMW B58 Turbo Blanket For BMW M140i, M240i, 340i, 440i & more

Maximise thermal efficiency and protect your engine bay with the Funk Motorsport Turbo Blanket for BMW and Toyota models equipped with the B58 single-turbo engine. Designed specifically for the complex twin-scroll turbocharger found in the B58 platform, this turbo blanket delivers superior heat management, improves turbo performance, and helps extend the life of nearby components. Crafted using a highly durable multi-layer construction — including a volcanic rock-based outer layer and stainless steel internal mesh — this turbo blanket is engineered to withstand sustained temperatures of up to 1300°C. By retaining heat within the turbo housing, it reduces heat soak, promotes quicker spool-up, and improves overall engine response, especially under high-performance conditions. Whether you're running a stock B58 engine or a tuned setup, this turbo blanket is a must-have upgrade to unlock reliable performance and keep under-bonnet temperatures under control. Supplied with stainless steel locking wire for secure installation and proudly developed in the UK. Notably, this turbo blanket is not single-use and can be removed and refitted during routine servicing.
