There are different conflicting views in this account. On the one hand, official dealers suggest that metal protection cannot be installed, because when the vehicle is hit, the engine must be freely blended down. Hard protection won't let him do it, and the engine might be in the salon. In other countries, however, this model is an original metallic protection.
Another view: the engine turbine must be considered by air, cooled down naturally. Metal protection, due to the structural peculiarities of the location of the turbine, will interfere with this process, which could lead to premature withdrawal of the turbine.
