Sorry to rain on your parade, but the SpiralMax (along with many other "As Seen On TV" car products) is worthless. There's multiple articles found on the net, along with other automotive BBs that prove this. If it works for you, cool... just watch out if you have some people (especially those who have been working on cars for some time) jump down your thought. Just wanted to make you aware, that's all... nothing personal.
BTW, good call saving for the CAI... you'll be very VERY happy with the results.
as far as the spiralmax, no i haven't really seen any power imporvement but i actually do seem to get a little better gas mileage. since it was only $59 and had a moneyback guarantee i thought why not give it a try... what kind of CAI should i try to get? do you know where the cheapest place to get them is?
Nice ride, I like the color. CAI's are a great mod, and they are actually one you can do yourself if money's tight. With a FWD 4-cylinder, it's not even that hard. Here's an example of a job a guy I know did on kind of a difficult car, an S12 200SX with a VG30 (like mine). I haven't done this job, but it's on the list. I'd think about opening up the exhaust as well.
