Intake and filter options

[Piper86]

I'm changing the induction on my car and would like to know the pro's and con's between wet and dry filters.
Also pro's and con's between, CAI, SRI and stock box with high flow filter and post MAF pipe.

I've already decided to do a turbo inlet pipe (Perrin or Mishimoto Rockstar ed)
Now I just need the rest.
My main aim is to get a smooth and drivable car and possibly safe on fuel after it is tuned for this setup as its used as a daily by my wife mostly.

Which combination if products can you recommend?

The car is a 2006 Subaru WRX STI.

The Cobb SRI with heatshield has proven to be very accurate for tuning. Do you have that as an option?

I'm in South Africa but will be ordering online probably from rallysportdirect.com
So yes COBB is an option. Still skeptical on the effectiveness of SRI though.

Wet or dry filters?
