I ordered this kit for the lower mounting position, without the symposer block off. The product arrived very well packaged and undamaged. The parts are clearly high quality, and everything went together exactly as the directions described. Hoses came with fittings that matched the Ford style fittings perfectly. This install took me a couple hours taking my time, but I would highly recommend. I have only had it for a couple thousand miles, so I have not checked it yet, but I see no issues with it so far.
