what is the best intake for a 2006 f250 6.0

[NYC F-350]

The stock one. Its a cold air intake and has the worlds BEST filter on it already.

Here is the response I have posted 3 times today already.
My background is in the Environmental field. You could say I understand how air filters work.

My advice is stay stock. It is already a "cold air" intake, more so than those overpriced kits. Those kits get the air from under the hood. Ever open the hood after running the truck for a bit? Was that air under there cold? Hardly.
Why does everyone think of a forced induction engine the same as a normally aspirated gas engine??
The turbo sucks the air in and pressurizes it to what the PCM tells it to achieve. Take off the entire intake and run it like that and guess what? You gained 0 horsepower, 0 torque. Again, the PCM tells the turbo to boost to whatever parameters are in the programming.
Now lets look at filtration. The stock filter is 99.97% effective down to 0.03 microns. Know how big that is? Yank a hair out of your head. That is about 100 microns across. now think about the particle size that the stock filter filters down to. You could put 3,000 pieces of that dust next to eachother and it would equal one hair. Thats kinda small, yes? Guess how small that is? That is the very same filter used in Hospitals, because most bacteria isn't that small. It is also the very same style of filter that you will see on the respirators used in Environmental Remediation. Lead and asbestos fibers that small are not aerodynamic enough to reach the depths of your lungs, so they get caught by your natural defenses and rejected by the body. Pretty slick, yes?
Want to look at flow? Well those cone style filters may flow a touch more than the stock filter. Sure, but lets remember the programming controls the turbo, so even if there is no filter, you still get the same horsepower number. The VGT (Variable Geometry Turbo) solenoid just wont have to close the vanes as much, but you are sucking dirt into your turbo.
There is no better than the stock intake for the FORCED Induction diesel engine, well unless your shooting for the "WOW" factor and trying to make the little girlies swoon when you pop the hood.......

Search "zoodad"

If you are looking for a different answer, I have an AEM Brute Force HD, and I love it. Nicely made, and no need to oil the filter.

My understanding is that the stock filter set up is the best up to 500hp. Do the zoodad mod and leave it at that. That's what I did anyways.
