Should come with a rubber insulator with a bolt through the middle. This holds the CAI to the engine bay.It also comes with a bracket that secures the vsv and associated hose. It's no biggie if this one is missing though. You can zip tie it up instead.
Yeah, The AEM came with the following:1 .Rubber extension that fits over the throttlebody and the intake as a connection (this comes with two hose clamps)2. The entire AEM intake tube with two washers and a bolt to secure it to the frame3. the cone filter with a hose clam to secure it to the tubeIf you picking up a used one, might want to recharge the filter with a cleaning kit
