I just drove and purchased a 2011 WRX 2 days ago...could not believe it, had no idea how amazing these cars are. Have been M3 fanatic for years, but am quickly rethinking that.
I am a new member, so bear with me...I know nothing about WRX's and need to learn. The one I purchased, 2011 with 22K miles appears in great shape.
Question is: under the hood is a blue COBB intake (left side when looking under hood). Is this stock or a mod, and if a mod does it boost HP?
Thanks, I appreciate it!
