RE: Replacement Air Filter
It's been installed for about a year and a half now, haven't noticed any vibration noise from day one. the results below are from an independent company, they did the test on a 2003 Dodge Ram HD2500, I have to say I did notice a considerable diffrence when I installed mine, I can't really say the results are as good as you see below, but the results are great.

RE: Replacement Air Filter
V8s don't compare well to I5s. The only AWD dyno in Detroit went under. Next closest is 4 hours away, so I am not in a hurry to do any dyno testing yet.
Realistically, with an I5 you should expect 2-5 HP with just a change to a performance filter (cotton gauze type), and another 5-12 HP when ditching the stock intake for a pipe.Torque should be similar, but not as much on the high end. Ditch the stock intake snorkel for a big mouth to the fender, and maybe more, that is what I want to test.

RE: Replacement Air Filter
I agree on the V8part for sure, an easy way to test your idea would be to just pull the cover of the filter box, you will have zero restriction on the filter box, at least it will tell you if it's worth doing something with the intake snorkel.

I think I'm going to go with this one

It's only about 200 bucks and the reviews look solid.

RE: Replacement Air Filter
If you use the Airaid system, you still have to use the lower half of the airbox. The guard around the filter that comes with the Airaid effectively seals off the filter from the rest of the engine compartment. That leaves you sucking air through the same hole in the bottom of the airbox. Have you seen that hole? It is about the same diameter as a silver dollar. What kind of an advantage is that? Especially if you use the stock tube from the filter to the engine. Get the K&N. They were the first. They are still the best. And they have dyno results to prove their claims. [sm=gears.gif]
