If there was a review you can trust, hope they improve their product. 1) The oil return line is too short. I had a great Parker hose lying around which is good for oil and fuel so I got around that 2) an insulated hose that runs front to back over the intake manifold, about 3/16 inch shorter, it was cut and used Hose and clamps lengthened to avoid over-stressing the knee it is connected to on an equalizing bar at the top of the manifold. 3) Some of the o-rings were too thick to fit. I had a set of metric o-rings I got from Napa and was able to assemble everything. Save your $40.
