intake for 99 sentra

I got a 99 Nissan Sentra EX, 1.6 automatic. I've been searchoing on the net for a cold air intkae system. BUt all of em for 200sx or se-r types. Can anyone reffer me a brand, model ?
It's like $55-60 on e-bay but if you go to the web sites around $150-250. It really make me confused!!!
And Have you guys heard about spiralmax? Which one do oyu recommend?

I'd say the cheapest way to go is to make your own cai

id reccommend Hotshot (http://www.hotshot.com), Place Racing (http://www.placeracing.com), Injen (http://www.injen.com), or you could do it yourself. but avoid all that e-bay crap. someone once told me "...you get what you pay for." so with that in mind, NEVER go with the cheapest piece-o-crap you see, instead do some research, and go with a reputible product that has been tested and proven.

As Ki$$ said, Hotshot Place Racing and Injen...they have parts that are dyno-tested and they fit.
