2000 Olds Alero CAI Kit

So I've been looking for a Cold Air Intake kit for my 2000 olds alero, I feel like i've looked everwhere and have had no luck, does anyone have any suggestions? Also i've had good luck with Ebay, and people have told me to purchase one off of Ebay, even though they are custom, they still sound and look the same and are ALOT cheaper?

Does anyone have any experiences with CAI's on Oldsmobiles?
