Please believe me, I do understand that cooler air+less flow restriction=better. This is basic theory. But theory often doesn't jive with practice. We have seen some evidence that the filter element itself makes very little difference, but we have been unable to seperate the effects from colder air intake from that of less restriction on flow. And we still don't have any quantitative evidence for the performance gains they are claimed to give. It is possible that the gain is so small as to not be worth the cost of the extra component and the time it takes to install them. Does this make since or am I just being confusing? Let me know and I will clarify.

anywho, i have almost completed my cai. hopefully i will be able to hit the dyno here in a bit and test the stock box w/ K&N drop in, K&N cone, and it plus the cai box after heatsoaking the engine bay.

Hurray! Finally.
I think my use of the word 'theory' might be a little different from some of you. It is like a theory in mathematics: so long as all the conditionals are true, the statement will be valid. I said theory because we really don't know that the conditions are being met; i.e. we are actually getting cooler air and less restriction. If we are, then yes, of course we will get a power gain. But making the assumption that one achieves these ends just by making a couple of mods is foolish. You actually have to test it- either by measuring the density of the intake air and the pressure differential from flow restriction, or by measuring power before and after which is easier and more usefull.
I can't wait to hear what you find out.

Great Not this debate again.... CAI > Intake boxes or Cold Intake boxes > Short Ram > Drop in filter
but since the FC dont have CAI made any more so all it is drop in filters. No matter what all suffer heatsoak but the CAI

EXACTLY! the box was unfinished it the pic by the way. Also, I run a standalone, so no AFM for me.

Has anybody thought of putting a hood scoop (discreet) in the hood section just above the air-box? And then doing a CAI chamber that seals to the hood? Would be a great ram-air setup.... I'm sure you'd still get heat-soaking a little bit, but with enough insulation on the engine bay, you could limit that considerably..
Just an idea... Might look cool too.
