I've got the Cobb stage 2+ package with the OTS map and that's close to 300 HP. FYI the forum bullies will tell you not do go with a CAI, but I recommend you do your own research and make your own call on that.Was wondering if anybody could help me out here. How much its roughly gonna cost to atleast get 300 whp out of a 2015 WRX MT. Already has a CBE. And the mods I should get.... Thanks in advance.
