I have an 05 wrx and I need to know the best cold air intake for it...thanks

So do they have a recirculating BOV then?

This is my first turbo car..I have a 2005 WRX. I am trying to find out if I am suppose to be able to hear the blow off valve release or not....I have done some research and not found out that answer. can anyone help.....thanks
