Great product

Awesome product would be great if it came with fittings for the price that you pay for it. Also instructions and ideas on what to run with different on setups.

Outstanding quality

As soon as this item arrived, I could tell from the packaging itself, it was going to be a superb item. The welds are flawless. The manifold is quite a bit heavier than I expected. But really, its a big hunk of aluminum so of course it has some weight to it. The ports on the bottom of the manifold are a nice added feature to add peripheral MAP based devices. As this is not an american company, the threads for the ports are BSPT instead of NPT so a bit more effort to find fittings and it is a bit annoying to have to source them rather than include several fittings and plugs. I ordered 4 1/8" BPST fittings and 1 1/4" fitting. The 1/4" fitting thread in just fine but the 1/8" fittings (2 plugs and 2 barbs) do not thread very well so I am off to grainger or fastenal to see if I can get something that threads right in. I would rather not tap new threads on a brand new ~2000$ item. The plenum is huge and the runners have nice fittings inside the plenum that are rounded for improved airflow. Very nice.
