Air box

[Wibrew cup]

In the process of removing the acoustic valve question is where the pipe went into the air box should I blank this off or leave it open

Please and thank you so much in advance for any help

If you mean the pipe that runs from the acoustic valve to the inlet then yes.

Iv already blanked that one off, the one that i am on about is the air inlet obviously there are two inlet pipes going into the air box do I need both of these or can I blank one off I would be more inclined to block the smaller one off cheers for the advice
