go for a CAI, you get better throttle responce & better gas mileage, too. not to mention more power & a better sound. as for brands, IT'S A TUBE!!!! the brand REALLY doesn't matter!! I have a generic 60 dollar setup off ebay, and a friend of mine w/ a 93 lude si (same as mine) wasted his $ on an AEM. we raced, and were tied through the whole quarter. unless you are brand name, car fashion obsessive, it doesn't matter at all.
