stock air intake pipes, whats this chamber for?

[mpturner1979]

Morning all,

 

Just a quick one, I replaced the air intakes pipes on my 2009 370Z over the weekend and fitted some silicone intake tubes, cant say I've noticed any difference in performance or sound, but hey ho, it kept me out of trouble for 45 mins.

The passenger side intake hose had an additional chamber (as per the photo), which the replacement silicone upgrade didn't accommodate for.

 

I was just curious, what does this chamber do? and if it does serve a purpose, why isn't it required on upgraded silicone intake pipes?

 

many thanks
