In an earlier post we criticized the British for supplying lackluster vent fans for the interior cabin. Truth is that the Italians are not totally innocent here either.
Behold photos of the original assembly that feeds air to the upper vents on the dashboard. As you can see the Italians were quick to assemble components that really did not fit well together. The result is an air passage that was about 10-15% blocked.
Easily corrected with an air saw however we are not expecting a massive improvement in ventilation. Either way every little bit counts.
