Mods on an automatic sedan?

[noraebong]

I am very new at performane mods..when I got my Yaris it was the frist car I had ever purchased, and I was looking simply for a reliable, fuel efficient econobox that would get me from A to B. My 07 Sedan (C package) has done well so far..evenin winter driving conditions.

Can anyone tell me what kind of HP a CAI and/or pulleywould add?

Thanks!

cali yaris reported a 12 WHP increase with the NST pulleys, CAI, DC Sports exhaust manifold and Tanabe axle-back exhaust.

I have the same setup and I can definitely say the car is more fun to drive than before. The pulleys make the engine a bit more responsive, and the other mods free up the air flow a little so the engine can breathe more easily. I noticed an improvement in power above 3,000 rpm. Also in my case, all these mods improved my gas mileage a bit... Light-weight wheels also help, as do good tires. And then you can improve the handling by lowering it and installing a sway bar. That won't give you more power, but it will feel like it, because the car will handle better, will be more stable, faster when turning, etc.

As for automatic vs. manual, I'm pretty sure the AT will handle a few extra ponies just fine
