the reason stillen intakes make more power over stock is it is tricking the ECU by mechanically leaning it out(like all intakes except for AEM) so the computer will only read X amount of air when there is really X+Y air(Y being the additional air not accounted for), and that combined with the cold air and better flow account for the rest of the gains
no the stillens are slightly bigger than OEM(OEM is 2.34 i believe stillen is 2.38)
if someone were to modify a stock airbox to fit on a SRI and completely seal it off from the engine bay, in theory it should outperform the long tube intake at speed because it is getting similar temps as the LTI and there is less restriction and in some cases(like fujita intakes), the short rams are physically larger than the long tubes are
EDIT these videos are pretty interesting

Lol the stillen doesn't trick the ecu, AEM does with the electric box they give you which is garbage. Doesn't matter the filter or the pipe size with the stillen, the MAF sees what it sees, period. The stillen isn't bigger or that really matters say you said 0.04" is nothing. Both are 2.5" OD, just depends how thick the material is which will change the ID but not enough to measure MAF scale or HP wise.

they have a pod filter episode as well and it shows pod filters dont flow any more than pannel filters

I agree with it does help coming from a certain point and not with it doesn't matter. If it didn't matter than having the radiator running in the summer would produce the same temps as in the winter. We're only talking about 20-40 degrees maybe difference but you can see big temp swings. Keeping the compressor housings as cool as possible will increase results. A cai even in a turbo car will be better than a sri in the engine bay.
