Performance of my '09

I have an '09 4 cyl, just wondering about some ways to get a good deal more hp and torque (mainly I just want some quicker acceleration) without compromising the mileage I get right around 24.9, and i dont want to lose that. Hell if i could increase that, it would be ideal!

Just let me know what you think I would benefit from. I dont have the greenery for a turbo-, super- charger so please refrain.

Thanks in advance!

 

you can remove the secondary air filter, pro dry filter r+r, i've heard cai are a waste of money, doug thorley header, cat back or muffler r+r should give you a lil boost, also do a search, HUNDREDS of threads on here about this
