Hey guys, as some of you know I got my wrx about 2 months ago at this point and this is my first car that i have wanted to add mods to and what not. I am ordering a cobb accessport and have been looking a different intakes and ram into a question about the two systems mentioned in the title. I know the aem mounts in the fender wall and there is the slight possibility of it sucking in water but that is very rare i heard and should not be a concern. The cobb system seems to mount in the stock air box or i could purchase the whole system with the airbox included. My question is, is the cobb worth buying with the airbox also or will it still function properly in the stock box if that is possible. Also anyone know if one system is better then the other when it comes to sound, performance, etc. ANy help would be great and if something i have stated is not clear let me know haha. Thanks!
