What is this middle intake port on a DOS av10 70cc kit

It looks as it doesn’t connect to the actual intake in the case like the other 2 and I’m just wondering what the purpose of it is

Those are all boost ports.

If they're not connected to the main boost tunnel coming out of the cases then you should connect them. I drill them to meet up then dremel to make it flowy.

You'll make more power
