I'd call this even on all fronts. Which is the usual result for air filter comparisons.
The filtration ability tests are normally NOT EQUAL however.

For the test did 3-5 pulls in each configuration. As the motor got hotter and hotter it made more and more power. We then would stop making pulls as the car stopped producing increasing power output.
The results of our tests are the highest readings that we gathered from each testing session. As it took a few min to swap out filters and so forth the car would cool off slightly, so doing an average would have not been accurate as it was anywhere between 1 min-5min between each batch of tests.
We felt that using the highest power producing runs between each test was the most accurate way to compare the data given the test environment and the limited data we where able to gather given no ECU monitoring software currently being available. I wish we had ECU data monitoring available as then we would be able to do complete testing with much better consistency, but we did with what we had at hand for the time being.
