ZACmotorsport’s guardian blanket is specifically designed and developed to fit around the sides and top of the pair of turbos on all M177/M178 engines. Adding a very effective and proven additional barrier. It is the best way to keep under bonnet temps down is to stop it from radiating in the first place.
Care has been taken to cover the turbine housing AND ONLY THE TURBINE HOUSING! This is very important as the blanket works by keeping exhaust heat inside! The thick cast housing can resist this heat. But other components on the exhaust such as dump pipes cannot handle the heat and will crack.
Turbo Blankets are proven to increase boost and therefore performance too
