Greetings,

Tha auxilliary air valve on the V12 is a temperature controlled air bypass valve that controls engine idle speed. It is located at the back of the left intake manifold, and draws inlet air from the left air cleaner only.

The balance pipe that connects the two intake manifolds at the rear distributes air equally to both sides of the engine: so even though most of the air at idle is entering through the left air cleaner only, all is well. If your engine performance is good, both air cleaner snorkels are sucking just fine as you drive down the road with the throttle plates open. All normal.
