I have a 2014 WRX Hatchback and i'm looking to put down at least 300 WHP. How can i achieve this?
I have been hearing alot of things about COBB CAI and COBB Accessport. Also about downpipes.
I'm looking into buying the invidia n1 race with the invidia downpipe how does the CAI and the Accessport work? What is this stage 1 stage 2 thing? Can someone help me clarify :P
