Agreed. The testing I did years ago, and reading about airflow testing of similar items bore out the same thing. Anytime you have minimal filter area, you are likely restricting airflow. And tea strainers aren't made for airflow. Besides, if you drive down a dusty road, they are only going to keep out rocks, not any small particles.

I know there are some newer style ones out that claim they aren't restrictive, but I haven't seen anything empirical or scientific to prove it. When you work so hard to make power on a 911, then kill of some hp just to run some inadequate filters makes no sense to me.
