A large diameter inlet pipe like the offerings from APS will yield more HP then any other inlet pipe type, air box or otherwise.

Turbo-Weapon, nobody is disputing your statements about ideal intake size and location.
On the other side, nobody is disputing that intakes make at most modest power on an otherwise nearly stock Evo.
The more controversial question is, if they are really making power, why do they make any power at all? Is it due to altered MAF readings or because of a genuine removal of a restriction?
Shiv, David Buschur and others have offered up some contradictory evidence so I wonder if anyone can offer up more controlled test results, especially any done while tracking air:fuel ratios across-the-board.

exactly..the intake tests done on a dyno will not yield much of anything.....I know of no dyno using a fan big enough to simulate 70 mph headwinds.
I know we have datalogged a couple setups with the HKS and ARC and spool times did decrease by a couple hundred rpm's.
Does that make it worthwhile? Surely not as much as an exhaust, but not a waste either.

Yes, people are correct, a Dyno will only measure the power increase, but who knows if that is due to the extra flow, or the colder air.
One way to be sure is to Data Log, with a bunch of sensors.
I would suggest a Air temp sensor in various positions under the bonnet, near and around the Filter Pod, and even inside the pod.
I would also use a AirFlow sensor, inside the pod, in one or more locations.
I think this would clear up many arrguments on which is the better intake setup, and why they are making power.
Surely, Cooler temp and Increased Flow should offer the best results.
However I strongly believe, that all those after market systems that place the Pod Filter under the bonnet, are a waste of time.
It may have the Flow, but can you not see it is sucking Hot Air.
Here is somebody that makes sense:
Lets add some more senors, a air temp senors before the IC cooler inlet and one at the outlet. Maybe your correct, maybe we dont need to suck cold air.
You are correct about the turbo, heating up the air!!
But only testing will show us ....
Now who has the time, and money, to modify there bits to fit all these sensors, on a number of different Intake systems .....

I do like the APS unit. Goes low into the bumper cover but my understanding is for turbo charged cars you really don't need to have a cold air intake because of the IC and because the turbo will make the air hot anyway.
