So, after having a few issues with my GTP (including having to get a new engine) I finally have enough money to start modding my car

I want to start off simple, nothing over a few hundred at a time for now, and am looking at getting a CAI, or some kind of intake. I was browsing through ebay and found multiple items like -

97-03 Grand Prix SE GT GTP 3.8 3.8L V6 Ram Air Intake u:eBay Motors (item 170385479179 end time Oct-20-09 19:14:13 PDT)

(There are multiple brands and whatnot, this is just one I picked to post.)


Can anyone atest to these? They seem like they would be nice, especially for the price, but would this not be a good investment?

I was looking at cars on cardomain.com, and happened to see -

And it looks like this one has the same kind of intake on it, and he says he can notice the performance increase.

Any comments/suggestions?
