JacFab - Laminator FX

I looked into a ported intake manifold for my Camaro, and the company that does the porting, also offers this drop-in piece that gives approximately a 17% increase in airflow as opposed to a 19-21% for a ported manifold ($100 VS $450). I watched the video on the site about this part and it really looks like this could be a DIY with some epoxy & a few screws.

If you could give the video a look and tell me what you think.

Thanks
