Stillen G3's aren't made that well. They have a nasty lip where they weld the tube expansion near the filter. Second, is it takes a lot of care to ensure you're protecting your AC line. This AEM unit is about as good as a shorty is going to get. The Z1 intake is an easier install with no real flaws for people going for the longer tube CAI option. You'll still make power with the G3, but it's not the answer for people who don't put up with **** craftsmanship.
