Heh.... yeah, those tests are always a kick. At best a cone filter in a box gives you the SAME performance as stock... Unless you've got a MASSIVE turbo and are sucking babies in you're not likely to significantly out flow a GOOD stock filter.

BTW - those links are both for the same video. Mind posting the other one you had intended on sharing?

I should mention that for those of you who want to test this out further and think you still can do better you can pick up a device used to measure pressure differentials across two reference channels called a manometer. Typically a good digital unit will run you in excess of $120 but you can find some which are good enough for this purpose starting around $40 on eBay. You'd measure the pressure right at the filter on the exterior and then at a reference port somewhere before the turbo or on a N/A before the throttle body. Measure at idle and then while driving around. Swap filters and repeat the last steps as closely as possible. The measurement you see on the meter represents the change in air pressure across the filter.
