I'm not sure what Z-Car Garage did to install the intakes, but it seems to me that they made the holes for the intake tubes way too large. I enlarged mine so that it is just barely large enough to fit and my intakes are very solid - no shaking whatsoever. Seems to me more of an install gone wrong than a problem on Stillen's side.
