manifold that cuts the air inlet in deceleration, to
avoid explosions in the muffler.
System description:
Air is sucked in through the hole "B" and gets
through the tube into the filter housing "C" where
the filtering element "D"is.
Now, the filtered air enters the diaphragm device
"A" and then is channelled to the head.
The air passes through a flanged pipe "E"connec-
ted to the air head and reaches a discharge joint
in order to supply oxygen to the unburned gases
before the catalytic converter, thus favouring an
improved reaction of the catalytic converter.
