Those just 5whp .. do not make stock looking in my eyes as THAT of a limiting factor due some supposed "major flaws".

Well I have datalogging that shows the problem. I made a test piece that removed the stock airbox and found a good improvement.
The other problem is some of the people doing aftermarket intake manifolds are just copying stock. If you polish a turd ... well its still a turd.
