My Mazda 6s

For some odd reason I've never been here before, but I really should have. I own a Black Mazda 6s and absolutely love it, I'm just curious as to what I should work on first. People say the exterior looks great, and I agree but a bigger spoiler would kind of suit my fancy. I've looked into engine/performance and am slowly becoming more and more pleased with the little oddities I'm finding. I'm planning on getting an Injen CAI and Exhaust system this summer. Then, there's always the interior. I guess what I'm saying is that I'm not really sure where to go first. So if this was your car what would you do?

Go for the CP-E MAFci!!!!!!!! 20+ wheel horse power for $539.
