Looking at the pics above, and still considering the small rectangular section of the AFM through which intake air goes, I just don't understand the effort - if people have to keep the stock AFM they may as well keep the stock airbox as it provides the most fresh air possible to the turbo.

I'm going for cold air velocity with ported head. A big flow 3" turbo is NOT what i have, nor a stock k26-6 and pipes.
A stock 951 in winter is MUCH faster than it is in summer FASTER THAN heat soaked intake at stoplights. (NOTHING TO DO WITH CFM FLOW or VACUUM)
getting ambient air from stock config is swell, but the box and filter inside is roasting, once its cooked the box enclosure keeps it cooked for awhile, even after you pull onto highway.
If Porsche designed that same box in the nose then its no problem with heat sink.
And the box traps water from wheel fender, oiled cone will get wet, yet will not puddle as stock snorkle or box (FACT)
Those chopped wide snorkle mods is neat mod, but it won't address the AFM restriction (THAT IS CFM FLOW problem, I don't care about this restriction, since my old MAF barely made a flow increase seeing that the IC has stock inlets and IC hard pipes same ID and kinks, I would think to increase flow one would have to change IC inlets first, manifold intake, then rest of the pipes and meter.
A MAF won't do, sinks resell value like most tuning kits and race parts. My friend make a bit more HP with big flow head and turbo, but he lags behind in 0-70, drinks gas with 55lb inj and costs was + $4000 to crank out maybe 30hp at top end 70mph -170mph with less reliability, less MPG, less resale appeal.
I rather have +30hp in a Millege CF intake manifold and larger intercooler, a turbo wrap, and a spare C02 bottle, a Quaiffe LSD, etc
