I just installed an AEM Cold Air Intake (stillen.com) on my 2003 Nissan Altima 2.5 automatic.
The sound is amazing (deep and throaty) and the RPMs bury when you hit the gas. Quiet in the city within low RPMs and a screamer when you step on it.
A great improvement!

What kind of improvement have you noticed performance wise. Are you getting better gas mileage?

I'm still on my first tank so I don't know the gas savings. As far as performance, it is a noticeable increase in accelaertion and agressiveness. When you step on it, the car growls (deep & throaty) at 4k RPM +. Like I said, its classey when rolling slow and mean when you hit it.
