I know and hear what you are saying, but do you really know? It 'sounds' right and it 'should' work but does it? What testing have you done to shows hard data and not just 'in theory'. How much CFM does the stock intake flow and how much thru the add on? Which direction does the ait flow thru the add on at speed? Just questions.

You milled pieces look great!
