2011 Mazda 3i 2.0l

I have a cai on the way. What other ways can i get a little more horsepower from this little motor? Header and exhaust? A tune? What are some of the options that you guys suggest?

A CAI goes well with an aftermarket cat-back exhaust.

Lighter wheels = faster acceleration

What brands do you suggest? I have had good luck with magnaflow on my mustang. I have some american racing wheels already

I remember reading when I had my 08 3' with the 2.3l there was a thing you could take out of the intake or something to increase the air flow, maybe even adjust the knock sensor or something to slightly increase the timing to speed up throttle response/reduce lag?
