I used to have a stock airbox CAI that used a length of 3" hose that went down to the foglight area. I retained my stock filter. It worked fine and it a great DIY option that is easy , affordable, and stealth.
I decided to fab up my own custom CAI with a piece of stainless pipe, more 3" hose and a K&N filter.
I did that for sound and as an excuse to do more things on my car
On your 2.0, I'd go with either a modded airbox w. the filter of your choice or, if you felt brave, a CAI like mine. A N/A engine does not want hot air, so an open-element intake would possibly rob your car of power.
