there are many different ways and circumstances in which cone intakes get employed. and it is obcerd to say that everyone of them is worse than the stock air box.
until you give me dyno numbers as to how much worse it is in our SPECIFIC APLICATION. im going to stay on the fence and exept that a pod filter (without a cold air box) sacrifice some intake temp for the sake of better flow. now when you factor in how the ecu reacts to that combo all bets go out the window on this kind os specualtion.
without extensive measurements it is imposible to tell to which extent this happens so realy ther is no need trying throw around your numbers like they mean anything that could be countered by an other aspect of a pod filter install.
I'm not entirely sure what the point of your post was. Are you attacking accuracy of my info or just me personally?

here's a fun bit of crap. the safc monitors the opening of the AFM. you stick a box around the cone filter and your afm opens up a helluva lot less. i'm not talking about the stock box either, just a heat shield type thing that is fitted to suck air in through the original nozzle area. im tempted to go stick my stock box on there just too see how much less the afm opens up.

i am much for not only having the filter away from the heat, but also wrapping the metal (metal! why metal?!) intake pipe with thermo-shield or similar heat wrap.
what do i have? the exact setup you say fails. bought the car used with one. i even still need the bracket to level the AFM.

they need a SECOND filter to catch oil! ... and the night grows older..
what time is it in australia, NZ? and do you have more than one time zone there?

Hah, I misread your post actually. I thought you were asking about both Australia and NZ. Shame on you!
Oz is our nickname for the big island next door. Australia, Aussie, Ozzie, Oz.

i figured it had to do with the aussies, but made no actual connection. wow, you broke it down step by step, though. something tells me this isnt the original intended topic. but i'm learning about internationality, and thats what this site is really for.

gotcha, NZ, I know what you're saying (in regards to my post). The ECU does know what to do, and it's just set to overcompensate. It's still kinda the same, as in, it's putting more fuel in than it should to prevent damage.
I was talking about non-turbo Subaru's, too, btw

Geez, you guys really hashed this one out.
What I am wondering now is if you could lean out the mixture at the higher rpms (say, 6500+) if you would get the power back. i.e. how much of the power loss is just due to the ECU being setup to run so rich at that airflow/air temp. Is the ECU being overly protective, or is it really necessary?

I cannot imagine needing to go THIS rich. What is really necessary?
