Air intake is controlled by a flap in the duct leading from the windshield to the airbox.
This flap reduces engine noise at low engine speeds.
The flap assembly is composed of: hatch / tie-rod / membrane / solenoid valve
The flap is normally closed and opens in the following circumstances:
minimum 6500 rpm
minimum 30 % throttle opening
The vacuum chamber acts to prevent pressure pulses.
If the check valve is to be replaced, take care to fit it in the correct position: the white part must be facing the vacuum
chamber.
