MFI airbox differences?
 

Getting ready to sell a stack of MFI airboxes and saw an outlier in the bunch. The blue one below seems to have an extra outlet for a hose at the back of the airbox. All the others I've seen look like the black one.

Anybody know what the extra port is all about?

Part of the canister/vent system. (At least on US spec 72)

These airboxes are all metal

Same deal, though - what else would it be for? :shrug:
