I'm getting lazy these days, and would rather do a link than re-type it all.
Take a look.

Sooo, what about the claimed , the air is cooler from lower in the fender well.
Cleaning the filter is a pain on the tube type, I was thinking of adding more tubing to bring it lower in the fencer well and easier to reach from below.

I used to run a MAC CAI on one of my Lincolns however the SMOG Nazi's would give me crap about it every time until I pointed out my "modified" CARB sticker. lol Now I just leave the stock air tube on there.. the OEM setup is technically a CAI as well. Just take the silencer thing out of the fender.

Well, if you think about it, the stock setup is the best "cold air" system available.
As long as the filter is sealed away from the engine compartment, lower in the fender is a moot point.
Live and learn.

a good way to check theories to me, would be to somehow measure the air both inside the filter box, and on a fender well cai unit. you would need reusluts from before, during, and after a w.o.t. run, or even just cruising. Armond, I would say get a 4" AFM powerpipe, but your bottleneck would be at the t/b. which kinda kills the use of it. theres gotta be some tech to tell which way is better on the net somewhere.

I hear you, Vic. It would be nice if there were some true before and after stuff out there. But everything I found was comparing apples to oranges. Swap a dirty paper filter for a new K&N and of course you'll show positive results.

I am confident that with the inside diameters being equal (well, slightly larger in the stock stuff) and with the panel being significantly larger than the cone, I have not lost anything.
And I definately like the look of the stock stuff.

You could make a direct measurement of the mass air sensor voltage. After all, that's what the ECU uses to calculate the flow. Then just compare voltages under identical conditions with the different pipe/filter arrangements. Keep the variables (RPM, manifold pressure,etc.) under control and you'll wind up with valuable reproducible data.

D'ya think BBK, K&N and the others might have already done this and they're just not letting us see the data?

Eh, who knows?
I did consider simply buying a taller -or larger if you will- filter, knowing it would flow more CFM. But that still left me with the hassle of the filter in the fender.
I also considered cutting a big hole in the fender for the filter to pass through. It would even have been hidden by the plate. But I did not want to do that either.

Separate but related; here's a link to some air filter testing that sure opened my eyes on the subject. The testing was simple and the results were only partly predictable.

My browser wouldn't copy html. It might be easier to find it with a google search for "air filter tests".

interesting read, how about take the cone filter off the air tube of the aftermarket CAI, fab a round filter into the tube or over it like you see on some stack type intakes, this would fit thru the fender opening, no need for enlarging the fender well hole and all you would need to do is unloosen the section closest to the fender well and pull thru to service the filter, i don't think you would lose air flow, the airflow goes from large cone type filter to smaller diam of the tube of the CAI. just a wild thought.
