BMW M235i Turbo Blanket N55 engine

The BMW N55 engine has been used in a huge selection of performance BMWs including BMW M135i, BMW F87 M2, BMW M235i, BMW 335i and BMW X5 xDrive 35i among many others! This high performance N55 engine is highly tunable and fast. The BMW N55 Turbo Blanket offers protection on both the Manifold and the turbo itself, allowing the two hottest parts of the engine bay to be protected and insulated. A turbo blanket REDUCES your under bonnet temperatures, creating MORE usable power throughout the entire RPM range, helping keep your surrounding components more RELIABLE, and helping to ACCELERATE the hot gases away from the engine.
The Turbo Jacket for the M235i, comes in 2 parts to provide MAXIMUM coverage and allow minimal heat soak. These Heat insulation blankets have been designed specifically for this turbo, unlike other manufacturers which utilise some one size fits all turbo blankets.
Check out our fitting guide of how to fit the BMW N55 blanket:
The M235i Turbo Blanket is based around the construction of the Mk3. Turbo blanket, which has reinvented the durability and performance of the turbo blanket. With an all new construction for 2020, thicker insulation, and a better all round aesthetic. Check out this video to see it in action on the Dyno!
Due to the close proximity between the two halves of the turbo, it is extremely common for heat sink to occur. This can decrease performance output while increasing the work of the input components during the combustion cycle. Funk Motorsport Turbo blankets are designed to keep the hot side of your turbo insulated while keeping the cold side at optimum temperatures. This helps to provide cooler airflow to the cooling system and MAF sensor, leading to an increased ignition spark and higher output of energy from combustion. By ensuring that the turbine sector of the turbo remains hot, less heat will be dissipated into the engine bay, ensuring that exhaust gases will flow with less turbulence from the exhaust.
