Subaru forester xt

[Matthat]

Hi, just noticed my forester makes a whooshing sound when I accelerate, it's not always there only under acceleration, it's not the turbo as car still has boost and can hear my bov, just want to know your thoughts.

 

Cheers

air intake

The hose? Or just the whole unit? Should upgrade, do I need a tune for a pod filter? Or cold air intake?
