does and "Air Filter" makes a difference?

They do very little -- computer adjusts for incoming air. Waste of money!

In day-to-day driving that is true. This is testing things at wide-open throttle, where the computer pretty much ignores everything but the airflow. More air in means more fuel added which means more power.
That said, I agree with you about waste of money. Most of us don't drive WOT.

Although I think this "test" was done rather fairly, there would be test engineers that would question viability because of potential driver influences in the acceleration evaluation. That aside, there are other web tests that appear to demonstrate a contradiction on the dyno test with the so called "high performance" filter types. One in particular is the video of dyno testing on a Mustang using the familiarly advertised "high performance" air filter of the type that requires an oil penetrant. In that test they actually realized lower HP and torque numbers in the low and midrange RPMs.
The big (in my opinion) question that remains is how efficient are the comparison filters in reducing unwanted foreign particles from entering the engine, and what are the effects on fuel consumption. The auto industry standard for air filtration is 2 microns. Over time I do not believe that high performance air filters that require oiling maintain the same level of filtration due to progressive oil loss, much less when freshly installed.
