came in a nice box. The expander itself is of good quality. The intake port on the spacer is noticeably smaller than the port on my intake manifold. (The big hole my finger is pointing at.) The instructions are confusing. The pictures in the instructions are of such poor quality that they are unreadable. The screws that come with the kit are a bit short, like the factory screws. So I have to drive to the hardware store if I want to install this at all. Comes with everything you see in my picture. **UPDATE** Went to the hardware store and bought 2 long screws for the front. One of the screws that came with the spacer was long enough for the stern.
