Pretty good quality overall with a few minor complaints. I didn't have any problems installing it, but it does take some effort to get the fittings aligned properly. They are pipe threads so you need to be careful not to overtighten them, there is a possibility of cracking the aluminum blocks that they thread into. ORB fittings would be much easier to work with. It doesn't come with gaskets, you'll need the Gen3 style gaskets. Installed height is about 1-5/8" above the top of the valley cover, so you'll need at least that much space below the intake. The tubes are a bit short, causing them to splay outwards when tightened. The bend on the outlet tube is kinked pretty bad, but not so much that it's closed off. All in all it's not terrible, it looks like it should work well.
