I ordered this spacer for my Cruze as part of the factory intake manifold PCV bypass fix, as described on CruzeTalk.com. It arrived in great condition and was well packaged. In addition to the spacer, it came with longer bolts to attach it to the existing throttle body, and a rubber gasket that fit perfectly into the machined groove. One minor concern was that the threads of the two threaded ports protruded slightly into the gasket groove. You couldn't see daylight through there, and with a gasket right there, I don't expect any leaks. It fit perfectly to my stock throttle body.
