Title: Useful & fun if not profitable
Review: It does work as advertised, but if you're looking for power increase and fuel savings, be realistic-- it will help but won't save enough fuel to pay for itself. Use it as part of a package (free flow exhaust, tweak the injector timing, etc.) and it will provide noticeable improvement. The main thing you'll notice-- either love or hate-- is the sound: You can hear the turbo whistling. Personally I like it. K&N is selling "the sizzle" as much as "the bacon," you can personalize your ride a little bit.
