What would you all say are the most important or your favorite things you've done to your MS3? Mine is still factory everything (2007 sport), I'm going to put in a K&N filter soon, but I'm just not sure what else to do.
Post your favorites (performance and looks) and I'll decide what I want to do. Thanks for your help!
