I originally had the Spectre CAI. I would say the tube, connectors are very similar. However, the filter on the Spectre is inferior to the AEM Dryflow. I replaced the filter and you can tell the AEM is much sturdier then the Spectre.
I believe the Spectre set up with the AEM dryflow is just about equal to the AEM set-up.
