I assuming you have engine management since you say you're at stage 2, but you should probably read the FAQ on why you shouldn't buy a cold air intake.
Not sure how much your setup is going to cost you but alternative option is.
Modded injectors and Walboro fuel pump.
Ebay FMIC which is supposedly identical to the TurboXS according to many on NASIOC.
A blouch 20G turbo with a new turbo inlet pipe.
I think this might be in the same range budget as your setup.
Oh and I say this again but Christian from Cobb did not make a VF34 map for the 06 WRX due to it being not as compatible or something along those lines.

I already read the CAI thread, I know the good and bad but see I am not just installing a cai, I am upgrading my turbo and tunning it. Intakes hurt you IF you are not tuned for it.
I doubt the power gains an intake would give you, tuned or not. Save the $$ and get a fuel pump instead. With aftermarket turbos you dont want to take any chances with your fuel.
I would get a walbro 90 bucks from gruppe-s. Cheap insurance imo. Also, people have been having great luck with the ebay fmic. Save some $$ for a little extra work.
I would go with the intake since you are upgrading the turbo,getting a protune,and have a 2.5. The stock box is rated for about 350-375 crank hp.A 2.5 WRX with a turbo upgrade will easily outflow the stock box.There is a reason 95% of STi's use an intake. Once they do a TBE and tune they are out flowing the stock box.The 2.5 WRX isn't far behind.

I agree, but it won't benifit you either. The stock set up now will get you air just as cold as the air in your fender. Just trying to save you some $.

Just for reference, The stock airbox on the 06 WRX is good for up to about 320 hp... so if you are going to exceed that... then yes it wouldn't hurt to get a CAI

I've rarely seen people break the 280whp mark on a good tune with the VF34. Most people I see get up to ~265whp. Again, the stock airbox with a high flow filter will work just as well unless he goes bigger.

Those are the kind of #'s a 2.0L pumps out with a VF34.He has a 2.5 not a 2.0.The biggest bottleneck on the 2.5 WRX is the stock TDO4-13T.
